TMEN
1 =
Enable test modes.
DIGLB
1 =
Tie the serial bit stream from the digital transmit filter output to the digital receive filter
input. DIGITAL LOOPBACK
ANALB
1 =
Tie the analog output of the transmitter to the analog input of the receiver. ANALOG
LOOPBACK
INTLB
1 =
Tie the digital serial bit stream from the analog receiver output to the analog
transmitter input. INTERNAL LOOPBACK
CkoutEn
1 =
Enable the CLKOUT output; 0 = CLKOUT tri-stated. For test purposes only; do not
use in normal operation.
RXPULL
1 =
Pulls DC Bias to RXAP/RXAN pins, thru 100Kohm each, to VREF, to be used in
testing Rx path.
0 =
No DC Bias to RXAP/RXAN pins
SPOS
1 =
Control frames occur after one quarter of the time between data frames has elapsed.
0 =
Control frames occur half way between data frames.
HC
1 =
FSB is under hardware control, bit 0 of data frames on SDIN is bit 0 of the transmit
word and control frames happen automatically after every data frame.
0 =
FSB is under software control, bit 0 of data frames on SDIN is a control frame request
bit and control frames happen only on request.
