Error protection is cancelled only by a reset or by hardware-standby mode. Note that the reset
should be released after the reset period of 100 µs which is longer than normal. Since high
voltages are applied during programming/erasing 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 damage to the flash memory by extending the reset period so that the charge is released.
The state-transition diagram in figure 14.16 shows transitions to and from the error-protection
state.
