11.4
11.4.1
Pins PO0 to PO15 are also used for other supporting functions such as the TPU. When output by
another supporting 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.
11.4.2
During non-overlapping operation, the transfer of NDR bit values to PODR bits takes place as
follows.
• NDR bits are always transferred to PODR bits at compare match A.
• At compare match B, NDR bits are transferred only if their value is 0. Bits are not transferred
Figure 11.10 illustrates the non-overlapping pulse output operation.
