Notes on Clock Supply to an MCU:
Clock can be supplied to the evaluation MCU in one of the following three ways. This is determined by
emulator debugger clock selection.
(1) When Internal is selected:
The clock generated by the oscillation circuit in the PC7501 is supplied to the evaluation MCU. The clock
is continually supplied to the evaluation MCU regardless of "user system clock status" and "user program
execution status".
(2) When External is selected:
The clock oscillating on the user system is supplied to the evaluation MCU. Clock supply to the evaluation
MCU depends on oscillation status (oscillate/off) of the user system.
(3) When Generate is selected:
A clock generated by the dedicated circuit in the PC7501 is supplied to the evaluation MCU. The clock is
continually supplied to the evaluation MCU regardless of "user system clock status" and "user program
execution status".
When operating this product with a sub clock, be sure to set the SW2 and SW3 to XCIN and NC, respectively.
Notes on Using the CPU Clock at Less than 10 MHz:
To use the CPU clock at less than 10 MHz, execute the command shown below in the Script Window after
starting the emulator debugger M3T-PD308F.
[Command]
_settimeout
,600
Once this command is executed, it remains effective the next time you start the emulator debugger M3T-
PD308F. Therefore, you do not need to execute this command again.
When you use the CPU clock at less than 1 MHz, contact your local distributor.
Notes on Address-Match Interrupt:
Do not single-step an address where an address-match interrupt occurs.
When using an address-match interrupt, do not select the check box of "Enable the Address Match Interrupt
Break Function" in the MCU tab of the Init dialog box. When not using an address-match interrupt, select the
check box.
When you use address-match breaks, if a low reset is input during a user program execution, a debug monitor
program (about 100 cycles) is executed after a reset is released. Take note that it has effects on the user program
execution time and the result of a trace.
