This register shows the "oldest" character stored in the receive buffer. On read-
ing, this character will not be removed from the buffer.

MR 13
Receive buffer, 8 bits (with deleting the character on reading)
This register shows the "oldest" character stored in the receive buffer. This char-
acter is removed from the buffer. Thus, the character received next can be read
out during the next read access.
