„Watchdog Timer
• External RC watchdog timer
1) Interrupt and reset signals selectable
• Internal counter watchdog timer
1) Generates an internal reset signal on overflow occurring in a timer that runs on a dedicated low-speed RC
oscillator clock (30kHz).
2) Three operating modes are selectable: continues counting, stops counting, or retains count when the CPU
„Clock Output Function
1) Able to output selected oscillation clock 1/1, 1/2, 1/4, 1/8, 1/16, 1/32, 1/64 as system clock.
2) Able to output oscillation clock of sub clock.
