6.1 Functions of 16-Bit Timer/Event Counters 00 and 01
(1) Interval timer
(2) PPG output
(3) Pulse width measurement
(4) External event counter
(5) Square-wave output
(6) One-shot pulse output
Note Available only for the
The
16-bit timer/event counters 00 and 01
• Interval timer
• PPG output
• Pulse width measurement
• External event counter
• Square-wave output
• One-shot pulse output
16-bit timer/event counters 00 and 01 generate an interrupt request at the preset time interval.
16-bit timer/event counters 00 and 01 can output a rectangular wave whose frequency and output pulse width can
be set freely.
16-bit timer/event counters 00 and 01 can measure the pulse width of an externally input signal.
16-bit timer/event counters 00 and 01 can measure the number of pulses of an externally input signal.
16-bit timer/event counters 00 and 01 can output a square wave with any selected frequency.
16-bit timer event counters 00 and 01 can output a one-shot pulse whose output pulse width can be set freely.
