18h: Misc Test Register 2 (Shadow Register Selector = “101”)
11 REMOTE LOOPBACK
TRISTATE
RW 1 = tristate the receive MII pins (CRS, RXDV,
RXD, etc.) when Remote Loopback is enabled
(only use in copper or fiber mode)
0 = Remote Loopback packets appear on MII
0
10 10BT WAKEUP RW 1 = enable 10BT dac 0
9 10BT POLARITY BYPASS RW 1 = enable polarity bypass
0 = normal operation
0
8 10BT IDLE BYPASS RW 1 = enable idle bypass
0 = normal operation
0
7 10BT CLOCK RESET
ENABLE
RW 1 = clock reset controlled from tpin11
0 = normal operation
0
6 10BT BYPASS ADC RW 1 = bypass 10BT adc
0 = normal operation
0
5 10BT BYPASS CRS RW 1 = bypass 10BT crs
0 = normal operation
0
4 SWAP RXMDIX RW 1 = rx and tx operate on same pair
0 = normal operation
0
3 HALFOUT RW 1 = transmit half amplitude, all speeds
0 = normal operation
also see exp reg f9.1
0
2:0 SHADOW REGISTER
SELECTOR
(REFERENCE ONLY)
RW Writes to the selected shadow register are done
on a single cycle (no setup required).
Reads are selected by first writing to register
18h, shadow 7, bits 14:12.
100
Bit Name RW Description Default
15 COPPER ENERGY
DETECT OVERRIDE
RW 1 = override copper energy detect
0 = normal operation
0

13 Class A/B DVT enable
(5478-A4/A5 and later)
RW 1 = enable, 0 = disable 0
12 CLASS A/B ENABLE
(100tx speed)
RW 1 = class AB txdac mode for 100tx speed
0 = class A txdac mode
See reg 18-2.15:13
