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 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.
(7) 24-bit external event counter
16-bit timer/event counter 00 can be operated to function as an external 24-bit event counter, by connecting 16-
bit timer/event counter 00 and 8-bit timer/event counter 52 in cascade, and using the external event counter
function of 8-bit timer/event counter 52.
When using it as an external 24-bit event counter, external event input gate enable can be controlled via 8-bit
timer counter H2 output.
