CHAPTER 8 8-BIT TIMER/EVENT COUNTERS 50, 51

8.1 Outline of 8-Bit Timer/Event Counters 50 and 51

8-bit timer/event counters 50 and 51 can be used as an interval timer, an external event counter, to output square
wave output with any selected frequency, and PWM output.

8.2 Functions of 8-Bit Timer/Event Counters 50 and 51

8-bit timer/event counters 50 and 51 have the following functions.
• Interval timer
• External event counter
• Square wave output
• PWM output
(1) Interval timer
These counters generate interrupt requests at the preset time interval.
(2) External event counter
These counters can measure the number of pulses of an externally input signal.
(3) Square wave output
These counters can output a square wave with any selected frequency.
(4) PWM output
These counters can output PWM.
Figures 8-1 and 8-2 show the 8-bit timer/event counter block diagrams.
