11.4 Usage Notes

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.

Note on Non-Overlapping Output: 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 if their value is 1.

Figure 11-10 illustrates the non-overlapping pulse output operation.
