8/16-bit PPG (Programmable Pulse Generator) Timers 0 and 1
The 8/16-bit PPG timer is a two-channel reload timer module (PPG0 and PPG1) that can generate pulse outputs
with the periods specified in the table below and with duty ratios between 0 and 100
%. Note that the pulse
periods are different depending on the operation mode.
*1 : 8
+ 8-bit PPG output operation mode consists of using the lower 8 bits as a prescaler for the PPG timer.
*2 : The values enclosed in ( ) indicate the times for a machine clock frequency of 16 MHz.
