14. Reset Input

During execution of the user program, the emulator may not operate correctly if a contention

occurs between the following operations for the emulator and the reset input to the target

device:

• Setting an Event Condition

• Setting an internal trace

• Displaying the content acquired by an internal trace

• Reading or writing of a memory

Note that those operations should not contend with the reset input to the target device.

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.
