Pins PO
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.
11.4.2
During non-overlapping operation, the transfer of NDR bit values to PODR bits takes place as
follows.
Figure 11.10 illustrates the non-overlapping pulse output operation.
Therefore, 0 data can be transferred ahead of 1 data by making compare match B occur before
compare match A. The NDR contents should not be altered during the interval from compare
match B to compare match A (the non-overlap margin).

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.
