Conflict between Buffer Register Write and Compare Match

If a compare match occurs in the T2 state of a TGR write cycle, the data transferred to TGR by the

buffer operation will be the write data.

Figure 14.50 shows the timing in this case.

Conflict between TGR Read and Input Capture

If the input capture signal is generated in the T1 state of a TGR read cycle, the data that is read

will be the data after input capture transfer.

Figure 14.51 shows the timing in this case.
