16-bit timer/event counter 00 has the following functions.
(1) Interval timer
(2) External event counter
(3) Pulse width measurement
(4) Square-wave output
(5) PPG output
(6) One-shot pulse output
Functions of 16-bit Timer/Event Counter 00
16-bit timer/event counter 00 generates interrupt requests at the preset time interval.
16-bit timer/event counter 00 can measure the number of pulses with a high-/low-level width of valid level
pulse width or more of a signal input externally.
16-bit timer/event counter 00 can measure the pulse width of an externally input signal.
16-bit timer/event counter 00 can output a square wave with any selected frequency.
16-bit timer/event counter 00 can output a square wave that have arbitrary cycle and pulse width.
16-bit timer/event counter 00 can output a one-shot pulse for which output pulse width can be set to any
desired value.
