23.5.18 Compare n Buffer Register
The TCEn.CMPnBUFL and TCEn.CMPnBUFH register pair represents the 16-bit value,
TCEn.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.
This register serves as the buffer for the associated compare registers (TCEn.CMPn). Accessing these registers using the CPU or UPDI will affect the corresponding CMPnBV status bit.
