Reserved
Transmit equalization selection bus for SerDes 1 lanes a–d (SD1_RX/TX[0:3])
Default value = 4’b0100
MSB (bit 16) is amplitude select:
0 = Vdd-diff-pk=pk
1 = 5/6 Vdd-diff-pk=pk
LSBs (bits 17:19) are equalization amplitude:
000 No equalization
001 1.09x relative amplitude
010 1.2x relative amplitude
011 1.33x relative amplitude
100 1.5x relative amplitude
101 1.71x relative amplitude
110 2.0x relative amplitude
