DESCRIPTION
For TI use only.
0 = Normal operation (Default 1’b0)
1 = Activates test pattern generation selected by bits 7.10:8
0 = Normal operation (Default 1’b0)
1 = Activates test pattern verification selected by bits 7.10:8
Test Pattern Selection
000 = Reserved
001 = Reserved
010 = Reserved
011 = CRPAT Long (Supported only in half/quarter/eighth rate modes).
100 = CRPAT Short (Supported only in half/quarter/eighth rate modes).
101 = 2⁷ - 1 PRBS pattern
110 = 2²³ - 1 PRBS pattern
111 = 2³¹ - 1 PRBS pattern (Default 3’b111)
0 = LOSx pin does not reflect AGC unlock status (Default 1’b0)
1 = Allows AGC unlock status to be reflected on LOSx pin
0 = LOSx pin does not reflect auto zero calibration not done status (Default 1’b0)
1 = Allows auto zero calibration not done status to be reflected on LOSx pin
Receive data replacement control during AGC unlock condition
0 = Data passed through as received (Default 1’b0)
1 = Data replaced with K30.7 (when decoder is enabled) or all 0’s (when decoder is
disabled)
Receive data replacement control during auto zero calibration not done condition
0 = Data passed through as received (Default 1’b0)
1 = Data replaced with K30.7 (when decoder is enabled) or all 0’s (when decoder is
disabled)
In this mode, serial input data traverses entire Rx datapath just before parallel
output drivers and is returned through entire Tx datapath and to the channel’s serial
output. The serial input data will also be available at the parallel output port. Serial
input data rate must match (0 ppm) reference clock.
0 = Normal functional mode (Default 1’b0)
1 = Enable deep remote loopback mode
See Figure 2-10
In this mode, serial input following decoder is fed back to the channel’s encoder
input and to the serial output. The serial input data will also be available at the
parallel output port. Serial input data rate must match (0 ppm) reference clock
0 = Normal functional mode (Default 1’b0)
1 = Enable shallow remote loopback mode
See Figure 2-10
In this mode, parallel input is looped after serializer and fed back to the channel’s
parallel output. The parallel input data is not available at the TX serial output. Note:
SWING[3:0] must be set to 4’b0000 in this mode.
0 = Normal functional mode (Default 1’b0)
1 = Enable deep local loopback mode
See figure Figure 2-9
Note that AZDONE must be asserted before asserting DEEP_LOCAL_LPBK. Also
note that AGCLOCK is not valid during DEEP_LOCAL_LPBK.
In this mode, parallel input after the encoder and before the serializer is fed back to
the channel’s parallel output. The parallel input data will also be serialized and
available at the TX serial port
0 = Normal functional mode (Default 1’b0)
1 = Enable shallow local loopback mode
See Figure 2-9
