hardware flow control. -RTS functions normally when
hardware flow control is disabled.
0 = Automatic RTS flow control is disabled. (normal
default condition)
1 = Enable Automatic RTS flow control.
EFR bit-7:
Automatic CTS Flow Control.
Logic 0 = Automatic CTS flow control is disabled.
(normal default condition)
Logic 1 = Enable Automatic CTS flow control. Trans-
mission will stop when -CTS goes to a logical 1.
Transmission will resume when the -CTS pin returns
to a logical 0.
