DESCRIPTION

Disables interrupts generated by Detect Register bits

D1 - D4 at INT pin in dual-port mode, or at INTRPT pin

in single-port mode. All interrupts normally disabled in

power down modes.

Enables interrupts generated by Detect Register bits

D1 - D4 at INT pin in dual-port mode, or at INTRPT pin

in single-port mode. An interrupt 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. The interrupt is reset

when the DR register is read.

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.
