Error protection is canceled by a reset. Note that the reset should be released after the reset input
period of at least 100µs has passed. Since high voltages are applied during programming/erasure
of the flash memory, some voltage may remain after the error protection state has been entered.
For this reason, it is necessary to reduce the risk of damaging the flash memory by extending the
reset input period so that the charge is released.
The state-transition diagram in figure 25.18 shows transitions to and from the error protection
state.
