Notes on MAP References and Settings:
• For details on referencing and setting MAP information, see User's Manual of emulator debugger
M3T-PD30.
•Be sure to set the SFR area to EXTERNAL.
•When setting 0FFFC16 to 0FFFF16 to EXTERNAL:
This product uses the 4 byte area 0FFFC16 to 0FFFF16 as the stack area when the RESET command
of emulator debugger M3T-PD30 is executed. If this 4 byte memory cannot be read or written to,
reset cannot be properly effected. As a result, you need to alter the map settings if the condition
given below is met.
(1) With the system which shifts from the single-chip mode to the memory expansion (or
microprocessor) mode, using the 4-byte area of 0FFFC16 to 0FFFF16 set to EXTERNAL.
(2) With the system which starts up in microprocessor mode, using the 4-byte area of 0FFFC16
to 0FFFF16 set to EXTERNAL and there is not enough memory to read or write.
The procedures to alter the MAP settings when the conditions (1) or (2) above are met.
(1) Set the 4-byte area of 0FFFC16 to 0FFFF16 to INTERNAL.
(2) Execute the RESET command by use of emulator debugger M3T-PD30.
(3) Set the stack pointer.
(Example)
RESET:
FCLR I
LDC #4000H, SP <-- Set the stack pointer
(Stop the program after executing this instruction)
(4) Set the 4-byte area 0FFFC16 through 0FFFF16 to EXTERNAL.
Notes on S/W Breaks and H/W Breaks:
•S/W breaks generate BRK interrupts by substituting the proper instruction to the BRK instruction.
Therefore, when referencing the result of a trace in bus mode, "0016" is displayed for the instruction
fetch address where a software break is set, and when referencing in reverse assemble mode,
"BRK" instruction is displayed.
• It is not possible to use a S/W break and a H/W break at the same time. If doing so, it may not operate
normally.
• In the area where the MAP setting is EXTERNAL, S/W breaks cannot be used.
Note on BRK Instruction:
• BRK instruction cannot be used.
