(5) Do not apply 12 V to the V
errors caused by accidental programming or erasing, apply 12 V to V
memory is programmed or erased, or when flash memory is emulated by RAM. While 12 V is
applied, the watchdog timer should be running and enabled to halt runaway program execution, so
that program runaway will not lead to overprogramming or overerasing.
(6) Disable watchdog-timer reset output (RESO
turned on. If 12 V is applied during watchdog timer reset output (while the RESO pin is low),
overcurrent flow will permanently destroy the reset output circuit. The watchdog timers reset
output enable bit (RSTOE) should not be set to 1.
If a pull-up resistor is externally attached to the V
reverse current from flowing to V
(7) If the watchdog timer generates a reset output signal when 12 V is not applied, the rise
and fall of the reset output waveform will be delayed by any decoupling capacitors
