Usage Notes

11.4.1

Operation of TPC Output Pins

TP0 to TP15 are multiplexed with 16-bit timer, DMAC, address bus, and other pin functions. When

16-bit timer, DMAC, or address output is enabled, the corresponding pins cannot be used for TPC

output. The data transfer from NDR bits to DR bits takes place, however, regardless of the usage

of the pin.

Pin functions should be changed only under conditions in which the output trigger event will not

occur.

11.4.2

Note on Non-Overlapping Output

During non-overlapping operation, the transfer of NDR bit values to DR bits takes place as

follows.

1. NDR bits are always transferred to DR bits at compare match A.

2. At compare match B, NDR bits are transferred only if their value is 0. Bits are not transferred

if their value is 1.

Figure 11.9 illustrates the non-overlapping TPC output operation.
