Section 8 Multifunction Timer Pulse Unit (MTU)
8.7.7
If a compare match occurs in the T2 state of a TGR write cycle, the data that is transferred to TGR
by the buffer operation differs depending on channel 0 and channels 3 and 4: data on channel 0 is
that after write, and on channels 3 and 4, before write.
Figures 8.73 and 8.74 show the timing in this case.
