Conflict between TPUm.TGRy Read and Input Capture
If the input capture signal is generated in a TGRy read cycle, the data that is read will be the data before input capture
transfer.
Figure 15.48 shows the timing in this case.

Conflict between TPUm.TGRy Write and Input Capture
If the input capture signal is generated in a TGRy write cycle, the input capture operation takes precedence and the write
