Function
010: 2.0 V.
011: 2.5 V.
100: 3.0 V.
The total range of the DAC extends from top-of-range, to top-of-range
minus the span. The span is set as:
00: 2.0 V.
01: 1.5 V.
10: 1.0 V.
11: 0.5 V.
DAC10B voltage control word (eight most significant bits).
DAC10Bvoltage control word (two least significant bits).
0: powers down DAC10A.
1: enables DAC10A.
Sets the DAC output voltage at the top range as follows:
000: 1.0 V.
001: 1.5 V.
010: 2.0 V.
011: 2.5 V.
100: 3.0 V.

Chooses the pattern type for the BIST sequence.
0: selects checker board pattern (0xA5A, 0x5A5, 0xA5A, …).
1: selects PRN output.
0: selects pattern input from internal pattern generator.
1: selects pattern from the external pins of the Tx port.
0: runs the BIST for 512 cycles.
1: runs the BIST continuously.
0: keep the BIST engine in an idle state.
1: start the BIST sequence.
0: disable the BIST engine.
1: enable the BIST engine.

0: selects checker board pattern (0xA5A, 0x5A5, 0xA5A, …).
1: selects PRN output.
0: selects pattern input from internal pattern generator.
1: selects pattern from the external pins of the Rx path.
0: runs the BIST for 512 cycles.
1: runs the BIST continuously.
