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

11.1
The H8S/2646 Group has a built-in 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
 Output trigger signals can be selected for each group from the compare match signals of
 A non-overlap margin can be provided between pulse outputs
 The compare match signals selected as output trigger signals can activate the DTC for
 Inverted data can be output for each group
 As the initial setting, PPG operation is halted. Register access is enabled by exiting module
