Section 11 Programmable Pulse Generator (PPG)
11.1 Overview
The H8S/2357 Group has a on-chip programmable pulse generator (PPG) that 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 (group 3 to group 0) that can
operate both simultaneously and independently.
11.1.1 Features
PPG features are listed below.
• 16-bit output data
 Maximum 16-bit data can be output, and output can be enabled on a bit-by-bit basis
• Four output groups
 Output trigger signals can be selected in 4-bit groups to provide up to four different 4-bit outputs
• Selectable output trigger signals
 Output trigger signals can be selected for each group from the compare match signals of four TPU channels
• Non-overlap mode
 A non-overlap margin can be provided between pulse outputs
• Can operate together with the data transfer controller (DTC) and DMA controller (DMAC)
 The compare match signals selected as output trigger signals can activate the DTC or DMAC for sequential output
of data without CPU intervention
• Settable inverted output
 Inverted data can be output for each group
• Module stop mode can be set
 As the initial setting, PPG operation is halted. Register access is enabled by exiting module stop mode
