CHAPTER 17 16-BIT PPG TIMER
17.1
Overview of 16-bit PPG Timer
The 16-bit PPG timer can generate a PWM (Pulse Width Modulation) output or one-shot
(square wave) output, and the period and duty of the output waveform can be changed
by software freely. The timer can also generate an interrupt when a start trigger occurs
or on the rising or falling edge of the output waveform.
■
16-bit PPG Timer
16-bit PPG timer can output the PWM output and the one shot. The output wave form can be reversed by
setting the register (Normal polarity
↔
Inverted polarity).

•
The count operation clock can be selected from eight different clock sources (MCLK/1, MCLK/2,
MCLK/4, MCLK/8, MCLK/16, MCLK/32, F
CH
/2
7
, or F

8
). (MCLK: Machine clock, F
CH
: Clock)
•
Interrupt can be selectively triggered by the following four conditions:
- Occurrence of a start trigger in the PPG timer
- Occurrence of a counter borrow in the 16-bit down-counter (cycle match).
- Rising edge of PPG in normal polarity or falling edge of PPG in inverted polarity
- Counter borrow, rising edge of PPG in normal polarity, or falling edge of PPG in inverted polarity
