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
12.1.

• Four output groups
• Selectable output trigger signals
• Non-overlap mode
• Can operate together with the data transfer controller (DTC) and the DMA controller (DMAC)
• Settable inverted output
• Module stop state can be set.
