according to the value of timer load register C. If it is not selected, timer C goes to $00. The timer C
interrupt request flag (IFTC: $002, bit 2) will be set as this overflow is output.
Timer C is also available as a watchdog timer for detecting runaway programs. MCU reset occurs when the
watchdog on flag (WDON) is 1 and the counter overflow output is generated by a runaway program. If
timer C stops, the watchdog timer function also stops. In the standby mode, this function is enabled.
Timer C provides a variable duty-cycle pulse output function (PWM). The output waveform differs
depending on the contents of the timer mode register and timer load register C (figure 28). When selecting
the pulse output function, set R3
1
/TIMO to TIMO by controlling port mode register B.
When timer C stops, this functions also stops.
