4.8 Low-Power Modes
The WAIT and STOP instructions will place the MCU in low power consumption standby modes.
4.8.1 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; however, no memory activity will take place since the CPU is inactive.
The WAIT instruction should not be executed while performing a program or erase operation on the
FLASH. Wait mode will suspend any FLASH program/erase operations and leave the memory in a
Standby Mode.
4.8.2 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; however, no memory activity will take place since the CPU is inactive.
The STOP instruction should not be executed while performing a program or erase operation on the
FLASH. Stop mode will suspend any FLASH program/erase operations and leave the memory in a
Standby Mode.

C. It is highly recommended that interrupts be disabled during
program/erase operations.
D. Do not exceed t
cumulative high voltage programming time to the same row before next
erase. t
max. Please also see
E. The time between each FLASH address change (step 7 to step 7), or the
time between the last FLASH address programmed to clearing the PGM bit
(step 7 to step 10) must not exceed the maximum programming time, t
max.
F. Be cautious when programming the FLASH array to ensure that
non-FLASH locations are not used as the address that is written to when
selecting either the desired row address range in step 3 of the algorithm or
the byte to be programmed in step 7 of the algorithm. This applies
particularly to:
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 minimum.
