RI
RI follows this bit when RIGPIOEN = 1
1 = RI can be used as a general purpose output and follows U7C[4] (RIGPO).
0 = Enables “No Loop Current” detect.
1 = Disables “No Loop Current” detect.
ATZ Disable.
0 = ATZ functions normally.
1 = Disable ATZ command.
FSK Data Processing.
0 = FSK data processing stops when carrier is lost.
1 = FSK data processing continued for 2 bytes after carrier is lost.
