mode, even by setting the P bit or E bit in FLMCR again. The PV and EV bits in FLMCR remain
valid, however. Transitions to verify modes are possible in the error-protect state.
The error-protect state can be cleared only by a reset or entry to hardware standby mode.
Note: * It is possible to write to these registers. Note that a transition to software standby mode
The purpose of error-protect mode is to prevent overprogramming or overerasing damage to flash
memory by detecting abnormal conditions that occur if the programming or erasing algorithm is
not followed, or if a program crashes while the flash memory is being programmed or erased.
This protection function does not cover abnormal conditions other than the setting conditions of
the flash memory error bit (FLER), however. Also, if too much time elapses before the error-
protect state is reached, the flash memory may already have been damaged. This function
accordingly does not offer foolproof protection from damage to flash memory.
To prevent abnormal operations, when programming voltage (V
