15. Contention between the Change of the FRQCR Register and the Debugging Functions
The following notes are required for the user program for changing the multiplication rate of
PLL circuit 1 to change the frequency:
• Avoid contention between the change of the FRQCR register in the user program and the
memory access from the [Memory] window, etc.
• When the automatic updating function is used in the [Monitor] window or [Watch] window,
generate and set a break of Event Condition for an instruction immediately before changing
the FRQCR register. Contention will be avoided by generating a break and executing the
user program again.
For the change of the multiplication rate of PLL circuit 1 and the FRQCR register, refer to the
hardware manual for the MCU.
