Page 355: Power-Up Led Displays
Power-Up LED Displays The system completes a series of tests and other functions whenever you turn on the system power. If the system halts at one of these functions, the diagnostic LEDs display a code that indicates where in the power-up sequence the system halted. Table D-33 lists the hexadecimal equivalent of the power-up LED displays and what they indicate about the power-up sequence.
Page 357 CPU and System Registers This appendix describes the CPU and system registers. The CPU and system registers contain information that can be useful when troubleshooting. There are two types of registers for the R3000: R3000A CPU registers and Model 100 system registers. The system automatically displays R3000A CPU register information on the screen when exceptions occur.

Page 362: Cause Register (R4000 Only
Cause Register (R4000 Only) The R4000 Cause register for the most part is the same as the R3000 register. The R3000 uses a 4-bit exception code (ExcCode) while the R4000 uses a 5-bit exception code (ExcCode). There is also some new exception codes. Table E-4 list the exception code and a description of each code.
Page 363: Exception Program Counter (Epc) (R3000 And R4000
Exception Program Counter (EPC) (R3000 and R4000) The EPC register for the R3000 and R4000 indicates the virtual address at which the most recent exception occurred. This register is a 32-bit read-only register that contains an address at which instruction processing can resume after an exception is serviced.
Page 364: Status Register (R3000 Only
Status Register (R3000 Only) The status register (SR) is a 32-bit read/write register that contains the kernel/user mode, interrupt enable, and diagnostic state of the processor. The SR contains a three-level stack (current, previous, and old) of the kernel/user (KU) bit and the interrupt enable (IE) bit.
Page 365: Diagnostic Status
machine dependent. For a description of the IP ﬁeld, see ‘‘Cause Register (R3000 Only)’’ on page E-3. KUo is the old kernel/user mode (0 = kernel, 1 = user). IEo is the old interrupt enable setting (0 = disable, 1 = enable).
Page 366 the IsC bit is set, store operations affect only the cache (main memory writes are inhibited), and load operations return the data at the addressed location in the cache, whether a cache miss occurs (main memory reads are inhibited). Uncached data references are not generally useful with IsC set.

The format of the diagnostic status ﬁeld is +-----------------+-----+----+----+----+----+-----+-----+ | BEV | TS | PE | CM | PZ | SwC | IsC | +-----------------+-----+----+----+----+----+-----+-----+ BEV controls the location of UTLB miss and general exception vectors (0 = normal, 1 = bootstrap). TS indicates that TLB shut down occurred.
Page 368 +------------+----+----+-----+-------+-----+-----+----+ | KX | SX | UX | ERL | EXL | IE | +------------+----+----+-----+-------+-----+-----+----+ The (CU) coprocessor usability ﬁeld is a 4-bit ﬁeld that individually controls the usability of each of the four coprocessor unit numbers (1 = usable, 0 = unusable). Coprocessor zero is always usable in kernel mode, regardless of the setting of the CU0 bit.

Page 370: Error Exception Program Counter (Error Epc) (R4000 Only
Error Exception Program Counter (Error EPC) (R4000 Only) The Error EPC register is similar to the EPC register, but it is used on ECC and parity error exceptions. It is also used to store the PC on Reset, Soft Reset and NMI exceptions. The address may be either: the virtual address of the instruction that caused the exception, or...

Page 372: Model 100 System Registers
Model 100 System Registers Data Buffers 3 to 0 The data buffers are general-purpose 32-bit read-write registers used by the I/O control ASIC. For test purposes, these registers can be read and written. Any DMA or access to a peripheral device can overwrite these registers.
Page 373: System Support Register (Ssr
System Support Register (SSR) The SSR can be both read from and written to. Bits <31:16> are used inside the I/O control ASIC. Bits <15:0> generate signals visible outside the I/O control ASIC. Table E-8. System Support Register 0x1C040100 Bits Access Description Communication port 1 transmit DMA enable...
Page 374 SSR<31> When set to 1, this bit enables communication port 1 (serial line 2) to transmit DMA to SCC(0)-B. Communication port 1 is the right comm port, viewed from the back. SSR<30> When set to 1, this bit enables communication port 1 (serial line 2) to receive DMA from SCC(0)-B.
Page 375 SSR<14:13> TXDIS These bits allow diagnostics to disable the EIA drivers on the serial lines. When TXDIS are 0’s, the EIA drivers are active. When TXDIS are 1’s, the EIA drivers are disabled. Since the TXDIS signals are automatically cleared at power up or reset, the EIA drivers are enabled by default.
Page 376: Leds Controlled By Ssr Leds Register Bits
<7:0> LEDS These bits determine the on/off state of the diagnostic LEDs. When a register bit is 0, the corresponding LED is on. When a register bit is 1, the corresponding LED is off. Since the LEDs bits are automatically cleared at power up or reset, all the LEDs are initially on.
Page 377: System Interrupt Register (Sir
System Interrupt Register (SIR) The SIR interrupt register consists of two sections. Bits <31:16> are set by the DMA engine for sundry DMA conditions. These bits are always set by the system and can be cleared by writing 0 to them. Writing 1 has no effect. These bits are cleared to 0 during system power up or reset.

Page 379 Table E-10 (Cont.). System Interrupt Register 0x1C040110 Bits Access Description SCSI data ready PBNC PBNO Communication port 1 is the same as serial line 2. Note: Communication port 2 is the same as serial line 3. SIR<31> This interrupt is generated by the communication port 1 transmit DMA logic.
Page 380 SIR<27> This interrupt is generated by the communication port 2 transmit DMA logic. The DMA transmitter, when enabled transmits bytes until the pointer reaches a page boundary. At this point it stops DMA and interrupts the processor. DMA is disabled whenever this bit is set. Clear this bit by writing 0; writing 1 has no effect.
Page 381 SIR<18> This bit is set when the buffer pointer is not reloaded soon enough. It indicates an overrun condition as the data buffer space is exhausted. DMA is disabled when this bit is set. Clear this bit by writing 0 to it. SIR<17>...
Page 382 SIR<10> NRMMOD This bit reﬂects the state of the manufacturing jumper on the module. When the jumper is absent, NRMMOD is 0, and the console should perform its normal power up or reset tests and boot. When the jumper is installed, NRMMOD is 1, and the console will execute manufacturing tests.
Page 383 SIR<2> This bit indicates SCSI receive data in the FIFO of the 53C94 SCSI controller. When transfers are aligned and the DMA is enabled, data is moved from the FIFO to main memory by the I/O control ASIC, and this interrupt is masked by software. Unaligned transfers cannot use DMA and thus cannot use this interrupt to signal when the processor must move data to memory.
Page 384: System Interrupt Mask Register
System Interrupt Mask Register Table E-11. System Interrupt Mask Register 0x1C040120 Bits Access Description 31:0 Interrupt mask <31:0> These bits, if 0, mask the corresponding interrupt observable in the SIR. Bit <0> masks SIR<0>, bit <1> masks SIR<1>, and so on.
Page 385: Memory Error Register (Mer
Memory Error Register (MER) The memory error register stores error information so that a bad memory card can be identiﬁed and replaced. Byte masks on writes to this register have no effect. The entire register is always written as a word. This register is visible in memory space and differs from all other system registers in one respect.
Page 386: Memory Size Register (Msr
MER<11:8> This ﬁeld indicates which byte or bytes had a parity error during a memory read. When set to 1, MER<11> indicates that memory data byte <31:24> is in error, MER<10> corresponds to memory data byte <23:16>, and so on. These bits is set on any memory access where an error occurred and remain set until they are cleared by writing them to 0.
Page 387: Error Address Register (Ear
Error Address Register (EAR) Table E-14. Error Address Register Register Console Address Description 0xAE000004 Error address register <28:2> The EAR contains address bits <28:2>, used to access memory at the time of a timeout or a memory parity error. Addresses stored in the EAR remain there until the next error condition is detected and a new address is stored.
