Watchdog Timer
Watchdog Timer
On detection of error, hardware reset is done inside the LSI
(Non-maskable interrupt is generated by the first watchdog time-out event, and hardware reset is
done by a series of two time-out events)
Time-out cycle
: CPU clock cycle  N ( N = 2¹⁶, 2¹⁸, 2²⁰, 2²⁷)
Watchdog Timer2
On detection of error, hardware reset is done inside the LSI
(Non-maskable interrupt is generated by the first watchdog time-out event, and hardware reset is
done by a series of two time-out events)
Time-out cycle
: Internal low-speed oscillation clock cycle  N
(N = 2⁴, 2⁵, 2⁶, 2⁷, 2⁸, 2⁹, 2¹⁰, 2¹¹, 2¹², 2¹³, 2¹⁴, 2¹⁵)
