Section 12 Programmable Pulse Generator (PPG)

The programmable pulse generator (PPG) provides pulse outputs by using the 16-bit timer pulse
unit (TPU) as a time base. The PPG pulse outputs are divided into 4-bit groups (groups 3 to 0) that
can operate both simultaneously and independently. The block diagram of PPG is shown in figure
