RS-422 / RS-485 Mode Support
Two additional modes of serial port operation are supported, these are:
RS-422 Mode – Full Duplex Serial Port for industrial applications
RS-485 Mode – Half Duplex Serial Port for industrial applications
RS-485
The RS-485 mode can be set using the Scratch
Pad Register bit[6] and bit[7] for each serial port.
This mode is a half duplex mode and the external
transceiver is controlled for transmission or
reception using the enable signal.

RS-422
This is the full duplex mode.
This mode will work without the use of the DTR
signal for external transceiver control.
