6.1 Functions of 16-Bit Timer/Event Counter 00
16-bit timer/event counter 00 is mounted onto all 78K0/Kx2-L microcontroller products.
16-bit timer/event counter 00 has the following functions.
(1) Interval timer
16-bit timer/event counter 00 generates an interrupt request at the preset time interval.
(2) Square-wave output
16-bit timer/event counter 00 can output a square wave with any selected frequency.
(3) External event counter
16-bit timer/event counter 00 can measure the number of pulses of an externally input signal.
(4) One-shot pulse output
16-bit timer event counter 00 can output a one-shot pulse whose output pulse width can be set freely.
(5) PPG output
16-bit timer/event counter 00 can output a rectangular wave whose frequency and output pulse width can be set freely.
(6) Pulse width measurement
16-bit timer/event counter 00 can measure the pulse width of an externally input signal.
