2.6.8 Stop Mode
Data Sheet
36
NOTE:
Putting the MCU into wait mode while the FLASH is in read mode does not affect
the operation of the FLASH memory directly, but there will not be any memory
activity since the CPU is inactive.
The WAIT instruction should not be executed while performing a program or erase
operation on the FLASH, or the operation will discontinue and the FLASH will be
on standby mode.
Putting the MCU into stop mode while the FLASH is in read mode does not affect
the operation of the FLASH memory directly, but there will not be any memory
activity since the CPU is inactive.
The STOP instruction should not be executed while performing a program or erase
operation on the FLASH, or the operation will discontinue and the FLASH will be
on standby mode
Standby mode is the power-saving mode of the FLASH module in which all internal
control signals to the FLASH are inactive and the current consumption of the
FLASH is at a minimum.
