CHAPTER 6 16-BIT TIMER/EVENT COUNTER 00
6.1
Functions of 16-bit Timer/Event Counter 00
16-bit timer/event counter 00 has the following functions.
(1) Interval timer
16-bit timer/event counter 00 generates interrupt requests at the preset time interval.
Number of counts: 2 to 65536
(2) External event counter
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.
Valid level pulse width: 2/fXP or more
(3) Pulse width measurement
16-bit timer/event counter 00 can measure the pulse width of an externally input signal.
Valid level pulse width: 2/fXP or more
(4) Square-wave output
16-bit timer/event counter 00 can output a square wave with any selected frequency.
Cycle: (2 to 65536) × 2 × count clock cycle
(5) PPG output
16-bit timer/event counter 00 can output a square wave that have arbitrary cycle and pulse width.
1 < Pulse width < Cycle ≤ 65536
(6) One-shot pulse output
16-bit timer/event counter 00 can output a one-shot pulse for which output pulse width can be set to any
desired value.
