Contention between Buffer Register Write and TCNT Clear
When the buffer transfer timing is set at the TCNT clear by the buffer transfer mode register
(TBTM), if TCNT clear occurs in the T2 state of a TGR write cycle, the data that is transferred to
TGR by the buffer operation is the data before write.
Figure 9.112 shows the timing in this case.
