DESCRIPTION
Selects 11.0592 MHz crystal echo output at CLK pin.
Selects 16 X the data rate, output at CLK pin in DPSK
modes only.
Selects normal operation. DPSK data is passed through
scrambler.
Selects Scrambler Bypass. DPSK data is routed around
scrambler in the transmit path. In V.23 mode, additional
phase equalization is added to the main channel filters
when D4 is set to 1.
Disables interrupt at INT pin.
Enables INT output. An interrupts will be generated with a
change in status of DR bits D1-D4. The special 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.
Selects an alternating mark/space transmit pattern for
modem testing.
Selects a constant mark transmit pattern.
Selects a constant space transmit pattern.
