Programmable Pulse Generator (PPG)
The programmable pulse generator (PPG) generates pulse outputs by using the 16-bit timer pulse unit (TPU) as a time
base.
The RX610 Group has two PPG units, each of which controls up to 16 pulse output pins. The pulse outputs from the
PPGs are divided into 4-bit groups that can operate all simultaneously and independently.

Overview
Table 16.1 lists the specifications of the PPG and table 16.2 lists PPG functions.
Figures 16.1 and 16.2 show block diagrams of the PPGs.
