Memory
2.6.7 Wait Mode
Putting the microcontroller unit (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.
2.6.8 Stop 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
46
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.
