Bit(s)
Name
Description
15:12
HS_SWING[3:0]
Transmitter Output swing control for HS Serdes. (Default 4’b1010)
Refer Table 6-6.
11
HS_ENTX
HS Serdes transmitter enable control. HS Serdes transmitter is automatically disabled
when PD_TRXx_N is asserted LOW or when register bit 1.15 is set HIGH.
0 = Disables HS serdes transmitter
1 = Enables HS serdes transmitter (Default 1’b1)
10
HS_EQHLD
HSRX Equalizer hold control.
0 = Normal operation (Default 1’b0)
1 = Holds equalizer and long tail correction in its current state
9:8
HS_RATE_TX [1:0] HS Serdes TX rate settings.
00 = Full rate (Default 2’b00)
01 = Half rate
10 = Quarter rate
11 = Eighth rate
7:6
HS_AGCCTRL[1:0] Adaptive gain control loop.
00 = Attenuator will not change after lock has been achieved, even if AGC becomes
unlocked
01 = Attenuator will not change when in lock state, but could change when AGC
becomes unlocked (Default 2’b01)
10 = Force the attenuator off
11 = Force the attenuator on
5:4
HS_AZCAL[1:0]
Auto zero calibration.
00 = Auto zero calibration initiated when receiver is enabled (Default 2’b00)
01 = Auto zero calibration disabled
10 = Forced with automatic update.
11 = Forced without automatic update
3
HS_ENRX
HS Serdes receiver enable control.
HS Serdes receiver is automatically disabled when PD_TRXx_N is asserted LOW or
when register bit 1.15 is set HIGH.
0 = Disables HS serdes receiver
1 = Enables HS serdes receiver (Default 1’b1)
2:0
HS_RATE_RX [2:0] HS Serdes RX rate settings.
000 = Full rate (Default 3’b000)
101 = Half rate
110 = Quarter rate
111 = Eighth rate
