• Manufacturer: Hitachi

11.1
The H8S/2646 Series 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
