When the flash memory is set to enter the module standby mode, the system clock supply is
stopped to the module, the function is stopped, and the state is the same as that in standby mode.
Also programming is stopped in the flash memory. Therefore operation program should be
transferred to the RAM and the program should run in the RAM. Then the flash memory should
be set to enter the module standby mode.
If an interrupt is generated in module standby mode, the vector address cannot be fetched. As a
result, the program may run away.
Before the flash memory is set to enter module standby mode, the corresponding bit in the
interrupt enable register should be cleared to 0 and the I bit in CCR should be set to 1. Then after
the flash memory enters the module standby mode, the NMI interrupt request should not be
generated.
