6. 8/16-bit PPG
• 8-bit PPG output in two channels independent operation mode:
• 16-bit PPG output operation mode :
• 8 + 8-bit PPG output operation mode : Variable-period 8-bit PPG output operation is available by using the
• PPG output operation :
(1) Register Configuration
8/16-bit PPG 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.
PPG0 operation mode control register channel 0 (PPGC0)
PPG1 operation mode control register channel 1 (PPGC1)
PPG0, PPG1 output control register channel 0, channel 1 (PPGOE)
Reload register upper channel 0, channel 1 (PRLH0, PRLH1)
Reload register lower channel 0, channel 1 (PRLL0, PRLL1)

Two independent PPG output channels are available.
One 16-bit PPG output channel is available.
output of channel 0 as the clock input to channel 1.
Outputs pulse waveforms with variable period and duty ratio. Can be
used as a D/A converter in conjunction with an external circuit.
