DESCRIPTION
D5 D4 D0
D5 interacts with bits D4 and D0 as shown. Also interacts
with DR bit D2 in originate mode (see Detect Register
description).
D5
Transmit
0 0 X
Disables answer tone generator.
Answer Tone
1 0 0
In answer mode, a Bell 2225 Hz tone is transmitted
continuously when the transmit enable bit is set.
1 0 1
Likewise, a CCITT 2100 Hz answer tone is transmitted.
D6
Transmit
0
Disables guard tone generator.
Guard Tone
1
Enables guard tone generator (see D0 for selection of
guard tones). Bit D4 must be zero.
D7
RXD Output
0
Enables RXD pin. Receive data will be output on RXD.
Control
1
Disables RXD pin. The RXD pin reverts to a high
impedance with internal weak pull-up resistor.
