Error protection is cancelled only by a power-on reset or by hardware-standby mode. Note that the
reset should only be released after providing a reset input over a period longer than the normal
100 s period. 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 18.16 shows transitions to and from the error-protection
state.
