Section 10 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 and 2)
that can operate both simultaneously and independently. Figure 10.1 shows a block diagram of the
PPG.
