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 0FFFC
This product uses the 4 byte area 0FFFC
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
(2) With the system which starts up in microprocessor mode, using the 4-byte area of 0FFFC
The procedures to alter the MAP settings when the conditions (1) or (2) above are met.
(1) Set the 4-byte area of 0FFFC
(2) Execute the RESET command by use of emulator debugger M3T-PD30.
(3) Set the stack pointer.
(4) Set the 4-byte area 0FFFC
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, "00
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.
