Usage Notes

15.5.1

Module Stop State Function

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 the module stop state. For

details, refer to section 28, Power-Down Modes.

15.5.2

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.

15.5.3

TPU Setting when PPG1 is in Use

When using PPG1, output toggling on compare-matches must be specified in the TIOR register of

the TPU that acts as the activation source and output must be selected as the PPG1 function.
