Clear bit
0: Normal operation (free-run)
1: Clear 8-bit counter (BITR) to “0”. This bit becomes 0 automatically
after one machine cycle, and starts counting.
Enable Peripheral clock
If this bit is 0, all peripherals are disabled such as Timer, ADC, PWM, etc.
0: Operate as a 6-bit general timer
1: Enable Watchdog Timer operation
See the section “Watchdog Timer”.
