Pulse Output Triggered by Input Capture

Pulse output can be triggered by TPU input capture as well as by compare match. If TGRA
functions as an input capture register in the TPU channel selected by PCR, pulse output will be
triggered by the input capture signal.
Figure 11.11 shows the timing of this output.

Usage Notes

11.5.1

Module Stop Mode Setting

PPG operation can be disabled or enabled using the module stop control register. The initial value
is for PPG operation to be halted. Register access is enabled by clearing module stop mode. For
details, refer to section 22, Power-Down Modes.
11.5.2

Operation of Pulse Output Pins

Pins PO0 to PO15 are also used for other peripheral functions such as the TPU. When output by
another peripheral function is enabled, the corresponding pins cannot be used for pulse output.
Note, however, that data transfer from NDR bits to PODR bits takes place, regardless of the usage
of the pins.
Pin functions should be changed only under conditions in which the output trigger event will not
occur.
