Chapter 12: Emulator Error Messages
Chip select 0 must have tcyc >=2 for map term 1 (Error 147)
Chip select 0 must have tcyc >=2 for map term 1 (Error 147)
Cause: You tried to enter a TCYC3-0 specification that is incompatible with the
present maximum bus speed and memory type. For the memory specified in the
emulation configuration (cf memtype) and the present bus speed specification
(cf maxbusspeed) all chip selects mapped into emulation memory must be
programmed for TCYC3-0 >= 2.
For max. bus speed 10MHz: Any chip select into emulation memory may be
programmed for any TCYC3-0.
For max. bus speed 25MHz: Any chip select into emulation memory must be
programmed for TCYC3-0 >=1.
For max. bus speed 33MHz, and Memory type HP64172: Any chip select into
emulation memory must be programmed for TCYC3-0 >=1.
Memory type HP64173 or for both type HP64172 and HP64173: Any chip select
into emulation memory must be programmed for TCYC3-0 >=2.
For max. bus speed 40MHz: Any chip select into emulation memory must be
programmed for TCYC3-0 >=2.
Action: Respecify the value of emor0 to obtain the correct TCYC3-0 programming.
Chip 0 has DRAM access into Map Term 1 (not allowed) (Status 169)
Cause: The setup of register emor0 allows DRAM access into emulation mapped
memory. The emulator does not allow this access.
Action: Write the correct value into register emor0 to prevent DRAM access into
emulation mapped memory.
Chip 0 has Parity enable into Map Term 1 (not allowed) (Status 170)
Cause: The setup of register embr0 enables parity checking into emulation mapped
memory. The emulator does not allow parity checking into emulation mapped
memory.
Action: Write the correct value into register embr0 to prevent parity checking into
emulation mapped memory.
