NAME

DESCRIPTION
D0
Equalizer
0
The adaptive equalizer is in its initialized state.
Enable
1
The adaptive equalizer is enabled. This bit is used in
handshakes to control when the equalizer should
calculate its coefficients.
D1
Train Inhibit
0
The adaptive equalizer is active.
1
The adaptive equalizer coefficients are frozen.
D2
RESET DSP
0
The DSP is inactive and all variables are initialized.
1
The DSP is running based on the mode set by other
control bits.
D3
16 Way
0
The receiver and transmitter are using the same decision
plane (based on the modulator control mode).
1
The receiver, independent of the transmitter, is forced
into a 16 point decision plane. Used for QAM
handshaking.
D4
Transmit S1
0
The transmitter when placed in alternating mark/space
mode transmits 0101...... scrambled or not dependent on
the bypass scrambler bit.
1
When this bit is 1 and only when the transmitter is placed
in alternating mark/space mode by CR1 bits D7, D6, and
in DPSK or QAM, an unscrambled repetitive double di-bit
pattern of 00 and 11 at 1200 bit/s (S1) is sent.
D5
Call Init
0
The DSP is set-up to do demodulation and pattern
detection based on the various mode bits. Both answer
tones are detected in demodulation mode concurrently;
TR-D0 is ignored.
1
The DSP decodes unscrambled mark, answer tone and
call progress tones.
0
Normal CR3 access.
D6
Special
Register
Access
1
Setting this bit and addressing CR3 allows access to the
special register (see the special register for details).
D7
Not used at this time
0
Only write zero to this bit.
