Selects normal operating mode
Analog loopback mode. Loops the transmitted analog
signal back to the receiver, and causes the receiver to
use the same center frequency as the transmitter. To
squelch the TXA pin, transmit enable must be forced
low.
Selects remote digital loopback. Received data is
looped back to transmit data internally, and RXD is
forced to a mark. Data on TXD is ignored.
Selects local digital loopback. Internally loops TXD
back to RXD and continues to transmit carrier from
TXA pin.
Selects normal operation.
Resets modem to power-down state. All
control register bits (CR0, CR1, TONE) are reset to
zero. The output of the CLK pin will be set to the
crystal frequency. This bit clears itself.
Selects 11.0592 MHz crystal echo output at CLK pin.
Selects 16 times the data rate, output at CLK pin in
DPSK modes only.
