FLASH Memory
Table 4-1. Protect Start Address Examples
BPR7–BPR0
Start of Address of Protect Range⁽¹⁾
$80
The entire FLASH memory is protected.
$81 (1000 0001)
$E040 (1110 0000 0100 0000)
$82 (1000 0010)
$E080 (1110 0000 1000 0000)
and so on...
$FE (1111 1110)
$FF80 (1111 1111 1000 0000)
$FF
The entire FLASH memory is not protected.
1. The end address of the protected range is always $FFFF.
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.
