14. Contention between the Change of the FRQCR Register and the Debugging Functions
The AUD pins are multiplexed with other pins. The AUD function cannot be used for the
initial values because they are used as other functions. To use the initial value as the AUD
function, set the AUD pins to be used from [AUD pin select] of the [Configuration] dialog box.
The emulator rewrites the registers in the pin function controller (PFC) to enable the specified
AUD pins before executing the user program. When those registers are changed by the user
program, take care so that the settings of the AUD pins is not changed. For details of the
setting methods and values, ask Renesas Technology Corp. via the sales office.
The WDT does not operate during a break.
Information in [JTAG clock] of the [Configuration] dialog box cannot be recovered by loading
sessions. Thus the TCK value will be 1.25 MHz.
Do not execute illegal instructions with STEP-type commands.
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.
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

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.
