20.5.18 Compare n Buffer Register
This register serves as the buffer for the associated Compare n (TCAn.CMPn) register. Writing to this register from the CPU or UPDI will set the Compare Buffer valid (CMPnBV) bit in the TCAn.CTRLF register.
The TCAn.CMPnBUFL and TCAn.CMPnBUFH register pair represents the 16-bit
value, TCAn.CMPnBUF. The low byte [7:0] (suffix L) is accessible at the
original offset. The high byte [15:8] (suffix H) can be accessed at offset +
0x01
.
