DESCRIPTION
Selects normal operation. DPSK and QAM data is
passed through scrambler.
Selects Scrambler Bypass. DPSK and QAM data is
routed around scrambler in the transmit path. In the V.23
mode, additional phase equalization is added to the main
channel filters when D4 is set to 1.
Disables interrupt at INT pin. All interrupts are normally
disabled in Power Down mode.
Enables INT output. An interrupt will be generated with a
change in status of DR bits D1-D4 and D6. 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.
