11.4 Usage Notes
11.4.1 Non-Overlap Operation
During non-overlap operation, transfers from the NDR to data registers (DR) occurs as follows.
1. NDR contents are always transferred to the DR on compare match A.
2. The contents of the bit transferred by the NDR are only transferred on compare match B when
they are 0. No transfer occurs for a 1.
Figure 11.9 illustrates the TPC output operation during non-overlap.
