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, through 100 k
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 =
FS 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 =
FS is under software control, bit 0 of data frames on SDIN is a control frame request bit
and control frames happen only on request.
