Selects normal operation. DPSK data is passed
through scrambler.
Selects Scrambler Bypass. Bypass DPSK data is
routed around scrambler in the transmit path.
Disables interrupt at
INT
pin.
Enables
INT
output. An interrupts will be generated
with a change in status of DR bits D1-D4. The answer
tone and call progress detect interrupts are masked
when the TX enable bit is set. Carrier detect is
masked when TX DTMF is activated. All interrupts will
be disabled if the device is in power-down mode.
Selects normal data transmission as controlled by the
state of the TXD pin.
