INITIALIZATION INTERFACE REGISTER
BIT(S)
NAME
DESCRIPTION
R/W
I.15 PHY A4
PHY address bit 4
I.14 PHY A3
PHY address bit 3
I.13 PHY A2
PHY address bit 2
I.12 PHY A1
PHY address bit 1
I.11 PHY A0
PHY address bit 0
I.10 10HDUP
10BASE-T half duplex initialization bit
1 = 10BASE-T (half-duplex) capability
0 = no 10BASE-T (half-duplex) capability
I.9 10FDUP
10BASE-T full duplex initialization bit
1 = 10Mb/s full duplex capability
0 = no 10Mb/s full duplex capability
I.8 100T4
100BASE-T4 initialization bit
1 = 100BASE-T4 capability
0 = no 100BASE-T4 capability
I.7 ISODIS
Isolate bit disable (bit 0.10)
I.6 REPEATER
Repeater mode: when this bit is set to 1,
CRS isonly asserted when receiving non-idle
signal at TPINP/N, and the ML6692 is
forced to half duplex mode
I.5–I.0 Not used
Note: Bits I<10:8> are the values for bits 1.11, 1.12 and 1.15 and initial values for bits 4.5, 4.6 and 4.9 of the MII Management Interface.

0 = disable auto negotiation
1 = power down
0 = normal operation
1 = electrically isolate the ML6692 from MII
0 = normal operation
1 = restart auto negotiation
0 = normal operation
1 = Full duplex select, auto negotiation disabled
0 = Half duplex select, auto negotiation disabled
1 = enable COL signal test
