Table 1. Initialization Interface Register
1 = electrically isolate the ML6692 from MII
10BASE-T half duplex initialization bit
1 = 10BASE-T (half-duplex) capability
0 = no 10BASE-T (half-duplex) capability
10BASE-T full duplex initialization bit
1 = 10Mb/s full duplex capability
0 = no 10Mb/s full duplex capability
100BASE-T4 initialization bit
1 = 100BASE-T4 capability
0 = no 100BASE-T4 capability
Isolate bit disable (bit 0.10)
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
1 = reset all register bits to defaults
0 = normal operation
1 = PMD loopback mode
0 = normal operation
1 = 100Mb/s
0 = 10Mb/s
1 = enable auto negotiation
0 = disable auto negotiation
1 = power down
0 = normal operation
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
0 = normal operation
