CHAPTER 6 16-BIT TIMER/EVENT COUNTERS 00 AND 01
The
µ
PD78F0132H incorporates 16-bit timer/event counter 00, and the
µ
PD78F0133H, 78F0134H, 78F0136H,
78F0138H, and 78F0138HD incorporate 16-bit timer/event counters 00 and 01.
6.1 Functions of 16-Bit Timer/Event Counters 00 and 01
16-bit timer/event counters 00 and 01
Note
have the following functions.
•
Interval
timer
•
PPG output
•
Pulse width measurement
•
External event counter
•
Square-wave
output
•
One-shot pulse output
(1) Interval
timer
16-bit timer/event counters 00 and 01 generate an interrupt request at the preset time interval.
(2) PPG
output
16-bit timer/event counters 00 and 01 can output a rectangular wave whose frequency and output pulse width can
be set freely.
(3) Pulse width measurement
16-bit timer/event counters 00 and 01 can measure the pulse width of an externally input signal.
(4) External event counter
16-bit timer/event counters 00 and 01 can measure the number of pulses of an externally input signal.
(5) Square-wave
output
16-bit timer/event counters 00 and 01 can output a square wave with any selected frequency.
(6) One-shot pulse output
16-bit timer event counters 00 and 01 can output a one-shot pulse whose output pulse width can be set freely.
Note Available only for the
µ
PD78F0133H, 78F0134H, 78F0136H, 78F0138H, and 78F0138HD.
