  • Page 33: Register Configuration

    Register Configuration The H8/300H CPU has the internal registers shown in figure 2-2. There are two types of registers; general registers and control registers. The control registers are a 24-bit program counter (PC), and an 8-bit condition code register (CCR). General Registers (ERn) ER7 (SP) Control Registers (CR)
  • Page 34: General Registers

    2.2.1 General Registers The H8/300H CPU has eight 32-bit general registers. These general registers are all functionally identical and can be used as both address registers and data registers. When a general register is used as a data register, it can be accessed as a 32-bit, 16-bit, or 8-bit register. Figure 2-3 illustrates the usage of the general registers.

The length of all CPU instructions is 2 bytes (one word), so the least significant PC bit is ignored. (When an instruction is fetched, the least significant PC bit is regarded as 0).

  • Page 37: Data Formats

    Data Formats The H8/300H CPU can process 1-bit, 4-bit (BCD), 8-bit (byte), 16-bit (word), and 32-bit (longword) data. Bit-manipulation instructions operate on 1-bit data by accessing bit n (n = 0, 1, 2, …, 7) of byte operand data. The DAA and DAS decimal-adjust instructions treat byte data as two digits of 4-bit BCD data.

    2.3.2 Memory Data Formats Figure 2-6 shows the data formats in memory. The H8/300H CPU can access word data and longword data in memory, however word or longword data must begin at an even address. If an attempt is made to access word or longword data at an odd address, an address error does not occur, however the least significant bit of the address is regarded as 0, so access begins the preceding address.

    Addressing Modes and Effective Address Calculation 2.5.1 Addressing Modes The following describes the H8/300H CPU. In this LSI, the upper eight bits are ignored in the generated 24-bit address, so the effective address is 16 bits. The H8/300H CPU supports the eight addressing modes listed in table 2-10. Each instruction uses a subset of these addressing modes.

    Basic Bus Cycle CPU operation is synchronized by a system clock (ø) or a subclock (ø ). The period from a rising edge of ø or ø to the next rising edge is called one state. A bus cycle consists of two states or three states.
  • Page 57: On-Chip Peripheral Modules

    2.6.2 On-Chip Peripheral Modules On-chip peripheral modules are accessed in two states or three states. The data bus width is 8 bits or 16 bits depending on the register. For description on the data bus width and number of accessing states of each register, refer to appendix B, Register Addresses. Registers with 16-bit data bus width can be accessed by word size only.
  • Page 58: Cpu States

    CPU States There are four CPU states: the reset state, program execution state, program halt state, and exception-handling state. The program execution state includes active mode. In the program halt state there are a sleep mode, and standby mode. These states are shown in figure 2-11, Figure 2-12 shows the state transitions.

    Section 3 Exception Handling Exception handling may be caused by a reset, a trap instruction (TRAPA), or interrupts. • Reset A reset has the highest exception priority. Exception handling starts as soon as the reset is cleared by the RES pin. The chip is also reset when the watchdog timer overflows, and exception handling starts.

  • Page 72: Reset

    Reset When the RES pin goes low, all processing halts and this LSI enters the reset. The internal state of the CPU and the registers of the on-chip peripheral modules are initialized by the reset. To ensure that this LSI is reset at power-up, hold the RES pin low until the clock pulse generator output stabilizes.
  • Page 73: Internal Interrupts

    WKP5 to WKP0 Interrupts WKP5 to WKP0 interrupts are requested by input signals to pins WKP5 to WKP0. These six interrupts have the same vector addresses, and are detected individually by either rising edge sensing or falling edge sensing, depending on the settings of bits WPEG5 to WPEG0 in IEGR2.

    Section 4 Address Break The address break simplifies on-board program debugging. It requests an address break interrupt when the set break condition is satisfied. The interrupt request is not affected by the I bit of CCR. Break conditions that can be set include instruction execution at a specific address and a combination of access and data at a specific address.

    6.2.1 Sleep Mode In the sleep mode, CPU operation is halted but the on-chip peripheral modules function at the clock frequency set by the MA2 to MA0 bits in SYSCR2. CPU register contents are retained. When an interrupt is requested, the sleep mode is cleared and interrupt exception handling starts. The sleep mode is not cleared if the I bit of the condition code register (CCR) is set to 1 or the requested interrupt is disabled in the interrupt enable register.
