processed
The sampling time can be set in the Extended Option dialog box.
The following shows the execution time, whereas the operating frequency = 5 MHz and PCC = 0.
When a clock is mounted on the 78K0-OCD board, power supply may not become the GND level even if the
power to the target system is shut down.
The POC function of the target device cannot be emulated. Make sure that the power to the target system is
not shut down during debugging

: Pseudo real-time RAM monitor function processing in progress
: User program is running.
: User program is running (sampling time − A − (A + B) × sampling range).
(during a break: RRM data collection and RRM data transmission)
One cycle = Several tens ms to several hundreds ms
A
The A period occurs for the number of the RRM point bytes + 1.
