54 FLASH Memory (FLASH) MOTOROLA
FLASH Memory (FLASH)
NON-DISCLOSURE AGREEMENT REQUIRED
4.10 Wait Mode
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.
4.11 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
NOTE: 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.
