This register sets up transmission according to characteristics of previous
reception instead of the LCR, DLL, and DLH registers used when UART is in
autobauding mode.
To reset the autobauding hardware (to start a new AT detection) or to set the
UART in standard mode (no autobaud), MDR1[2:0] must be set to reset state
111, and then to the UART in autobaud mode 010 or UART in standard mode
000.
Usage limitation:
Only 7- and 8-bit character (5 and 6 bits not supported)
-
7-bit character with space parity not supported
-
Baud rate between 1200 and 115200 bp/s (10 possibilities)
-
