In 16-bit mode, this register holds bits 8–15 of the hardware match buffer. In 8-bit mode, writes to this register will be
ignored.
Holds bits 0–7 of the hardware match buffer.
In 16-bit mode, this register holds bits 8–15 of the data to be transmitted by the transmit buffer and received by the
receive buffer.
Holds bits 0–7 of the data to be transmitted by the transmit buffer and received by the receive buffer.
