Refer to UART chapter for operation
Driver Enable Polarity
0 = DE signal is active High
1 = DE signal is active Low
Multiprocessor Bit Transmit
0 = Send a 0 as the multiprocessor
bit
1 = Send a 1 as the multiprocessor
bit
Multiprocessor Mode [0]
See Multiprocessor Mode [1] below
Multiprocessor (9-bit) Enable
0 = Multiprocessor mode is disabled
1 = Multiprocessor mode is enabled
Multiprocessor Mode [1]
with Multiprocess Mode bit 0:
00 = Interrupt on all received bytes
01 = Interrupt only on address bytes
10 = Interrupt on address match and
11 = Interrupt on data following an
Mulitprocessor Receive
Returns value of last multiprocessor
