10.3.17 Timing of Buffer Register (BFR) Write and Transfer by Buffer Function
In channels 6 to 9, if the BFR value is transferred to the duty register (DTR) by a compare-match
with the cycle register (CYLR) in the T2 state during a write cycle from the CPU to the buffer
register (BFR), the value prior to the CPU write to BFR is transferred to DTR.
The timing in this case is shown in figure 10.29. In this example, a CYLR compare-match and a
write of H'AAAA to BFR occur simultaneously when the BFR value is H'5555.
