6. 8/16-bit PPG
This block is an 8-bit reload timer module. The block performs PPG output in which the pulse output is controlled
by the operation of the timer.
The hardware consists of two 8-bit down-counters, four 8-bit reload registers, one 16-bit control register, two
external pulse output pins, and two interrupt outputs. The PPG has the following functions.
8-bit PPG output in two channels independent operation mode:
Two independent PPG output channels are available.
16-bit PPG output operation mode
: One 16-bit PPG output channel is available.
8+8-bit PPG output operation mode
: Variable-period 8-bit PPG output operation is available by using the
output of channel 0 as the clock input to channel 1.
PPG output operation
: Outputs pulse waveforms with variable period and duty ratio. Can be
used as a D/A converter in conjunction with an external circuit.
