Note On Clock Supply To The Mcu; Notes On Interruption - Renesas M302N1 User Manual

Note on Clock Supply to the MCU:

• Clock can be supplied to the evaluation MCU in one of the following two ways. This is determined
by emulator debugger clock selection.
(1) When Internal is selected:
(2) When External is selected:

Notes on Interruption:

• Even when the target program is not being executed (while the target program is stopped or during
runtime debugging), the emulation MCU keeps running so as to control the emulation pod.
Therefore, note that timers and other components do not stop running even though the target
program is not being executed.
• If a maskable interrupt request is generated when the target program is not being executed (while
the target program is stopped or during runtime debugging), the request is not accepted because the
emulator disables all interrupts. If an interrupt request is generated when the target program is not
being executed, but the target program enables that interrupt, it will be accepted immediately after
program execution starts.
IMPORTANT
The clock generated by the oscillation circuit in the emulation pod is supplied to the evaluation
MCU. The clock is continually supplied to the evaluation MCU regardless of "target system
clock status" and "user program execution status".
Clock supply to the evaluation MCU depends on oscillation status (oscillate/off) of the target
system.
