9.7.10
If an input capture signal is generated in the T2 state of a TGR write cycle, the input capture
operation takes precedence and the write to TGR is not performed for channels 0 to 4. For channel
5, write to TGR is performed and the input capture signal is generated.
Figures 9.115 and 9.116 show the timing in this case.
