21C.10.3 Error Protection
In error protection, an error is detected when chip runaway occurs during flash memory
programming/erasing, or operation is not performed in accordance with the program/erase
algorithm, and the program/erase operation is aborted. Aborting the program/erase operation
prevents damage to the flash memory due to overprogramming or overerasing.
If the chip malfunctions during flash memory programming/erasing, the FLER bit is set to 1 in
FLMCR2 and the error protection state is entered. The FLMCR1, FLMCR2, EBR1, and EBR2
settings are retained, but program mode or erase mode is aborted at the point at which the error
occurred. Program mode or erase mode cannot be re-entered by re-setting the P or E bit. However,
PV and EV bit setting is enabled, and a transition can be made to verify mode.
FLER bit setting conditions are as follows:
1. When the flash memory of the relevant address area is read during programming/erasing
2. Immediately after exception handling (excluding a reset) during programming/erasing
3. When a SLEEP instruction (including software standby) is executed during
Error protection is released only by a reset and in hardware standby mode.
