• Manufacturer Part Number: h8s-2635
• Description: Renesas 16-bit Single-chip Microcomputer H8s Family/h8s/2600 Series
• Manufacturer: Renesas Electronics Corporation.

Note: The H8S/2635 Group is not equipped with a PPG.
11.1
The chip has an 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 and group 2) that can operate both simultaneously and independently.
11.1.1
PPG features are listed below.
8-bit output data
Two output groups
Selectable output trigger signals
Non-overlap mode
Can operate together with the data transfer controller (DTC)
Settable inverted output
Module stop mode can be set
Maximum 8-bit data can be output, and output can be enabled on a bit-by-bit basis
Output trigger signals can be selected in 4-bit groups to provide up to two different 4-bit
outputs
Output trigger signals can be selected for each group from the compare match signals of
four TPU channels
A non-overlap margin can be provided between pulse outputs
The compare match signals selected as output trigger signals can activate the DTC for
sequential output of data without CPU intervention
Inverted data can be output for each group
As the initial setting, PPG operation is halted. Register access is enabled by exiting module
stop mode
