Contention between TGR Read and Input Capture: If the input capture signal is generated in the T
read cycle, the data that is read will be the data after input capture transfer.
Figure 10-53 shows the timing in this case.
Contention between TGR Write and Input Capture: If the input capture signal is generated in the T
write cycle, the input capture operation takes precedence and the write to TGR is not performed.
Figure 10-54 shows the timing in this case.
