PPG Timer
The PPG timer can output highly accurate PWM waveforms efficiently.
This device contains six PPG timer channels and its features are as follows :
Each channel consists of a 16-bit down counter, a 16-bit data register attached with a frequency setting buffer,
a 16-bit compare register attached with a duty setting buffer, and a pin controller.
The count clock for the 16-bit down counter can be selected from the following four types :
Internal clocks
φ
,
φ
/4,
φ
/16, and
φ
/64
The counter value can be initialized by reset or counter borrow to “FFFF
H
.”
PWM output (by channel)
DMA transfer can be invoked by interrupt.
