When I startup the emulator debugger (PDB77, SDB77P) I get one of two messages: "Error 1110: Cannot execute specified

command normally (can not execute the pre-process for this command execution)", "Error 1111: Cannot execute specified

command normally (cannot release MCU HOLD)." What is the problem?

Please examine the following problems.

(If the target system is not connected at this time, #3 will not occur.)

Emulator System (hardware) Setup Problems

--->The board attached to the PC4816B internally may not be correctly inserted into the slot. Check the connection carefully.

--->The 100-pin half-pitch cable may not be correctly connected between PC4816B and M377XXTX-HPD. Check the

connection carefully.

Emulator Debugger (PDB77, SDB77P) Setup Problems

--->The MCU information may not be set properly.

Please confirm the contents of the setting. For details, refer to "M377XXTX-HPD Handling Instructions: MCU Command

Description Examples Section".

--->The mapping may not be setup correctly.

Please keep the following emulation usage limitations in mind when checking the contents of each setting.

When using the emulator, the emulator will need part of the MCU memory space as a work area. This work area (1 - 6 as

indicated below) must be set for the MCU to be able to perform an access.

6 bytes of user stack area (the 6 bytes lower than the address indicated by the stack pointer)1.

DBC vector area (FFF8H to FFF9H)2.

BRK vector area (FFFAH to FFFBH)3.

RESET vector area (FFFEH to FFFFH)4.

Monitor work area in Bank 0 (arbitrary 6 bytes)

The start address of the monitor work area in Bank 0 can be set to any address by the emulator debugger.

Debug Bank (any one bank)

The debug bank can be set to any bank by the emulator debugger.

[Mapping Setup Example]

C000 to FFBF R/W EXT

FFC0 to FFC5 R/W INT ; Monitor work area in Bank 0

FFC6 to FFF7 R/W EXT

FFF8 to FFFB R/W INT ; DBC, BRK vector area

FFFC to FFFD R/W EXT

FFFE to FFFF R/W INT ; RESET vector area

10000 to FEFFFF R/W EXT

FF0000 to FFFFFF R/W INT ; Debug bank

Target System Problems

--->The target system supply power may not be within the guaranteed operating range. Check the operating voltage.

For more details considering guaranteed operating conditions, refer to M377XXTX-HPD Handling Instructions:

Specifications Section.

--->There may be a problem concerning the target system pins. Please verify the following items:

- Make sure the RESET, HOLD, and RDY pins are 'H' during the emulator debugger startup (while setting MCU

information).

❍

- Make sure BYTE pin is set to proper bus width state.

When using single-chip mode, memory expansion 16-bit bus mode, or microprocessor 16-bit bus mode, the BYTE pin

must be 'L'. When using memory expansion 8-bit bus mode or microprocessor 8-bit bus mode, the BYTE pin must be

'H'.
