IMPORTANT
Notes on Using the CPU Clock at Less than 16 MHz:
• To use the CPU clock at less than 16 MHz, execute the command shown below in the Script Window after
starting the emulator debugger M3T-PD308F.
[Command]
_settimeout ,300
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.
