• Manufacturer Part Number: HD6412320
• Description: Renesas 16-Bit Single-Chip Microcomputer H8S Family H8S-2300 Series
• Manufacturer: RENESAS [Renesas Technology Corp]

11.1
The chip 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 to group 0) that can operate both simultaneously and independently.
11.1.1
PPG features are listed below.
• 16-bit output data
• Four output groups
• Selectable output trigger signals
• Non-overlap mode
• Can operate together with the data transfer controller (DTC) and DMA controller (DMAC) *
• Inverted output can be set
• Module stop mode can be set
⎯ Maximum 16-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 four 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 or
Note: * The DMAC is not supported in the H8S/2321.
⎯ Inverted data can be output for each group
⎯ As the initial setting, PPG operation is halted. Register access is enabled by exiting module
