Non-Overlapping Pulse Output

During non-overlapping operation, transfer from NDR to PODR is performed as follows:

• At compare match A, the NDR bits are always transferred to PODR.

• At compare match B, the NDR bits are transferred only if their value is 0. The NDR bits are

not transferred if their value is 1.

Figure 11.6 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-overlapping margin).

This can be accomplished by having the TGIA interrupt handling routine write the next data in

NDR, or by having the TGIA interrupt activate the DTC or DMAC. Note, however, that the next

data must be written before the next compare match B occurs.
