 Watchdog Timer
Watchdog Timer
On detection of error, hard reset is done inside the LSI
(Non-maskable interrupt is generated by the first watchdog time-out event, and hard-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, hard reset is done inside the LSI
(Non-maskable interrupt is generated by the first watchdog time-out event, and hard-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)
