Receive Data Register Value
RBUF contains the received data bits and,
depending on the selected mode, the parity bit in
asynchronous and synchronous operating mode of
the ASC.
In asynchronous operating mode with M = 011
(7-bit data + parity) the received parity bit is written
into RD7.
In asynchronous operating mode with M = 111
(8-bit data + parity) the received parity bit is written
into RD8.
