MDDIS
I
Management Data Disable.
When MDDIS is High, the MDIO is disabled from read and write
operations.
When MDDIS is Low at power-up or reset, the Hardware Control
Interface pins control only the initial or “default” values of their respective
register bits.
After the power-up/reset cycle is complete, bit control reverts to the
MDIO serial channel.
43
MDC
I
Management Data Clock.
Clock for the MDIO serial data channel.
Maximum frequency is 8 MHz.
42
MDIO
I/O
Management Data Input/Output.
Bidirectional serial data channel for PHY/STA communication.
64
MDINT_L
OD
Management Data Interrupt.
When register bit 18.1 = 1, a Low output on this active-low pin indicates a
status change.
Interrupt is cleared by reading Register 19.

O
Twisted-Pair Outputs, Positive and Negative.
During 100BASE-TX or 10BASE-T operation, TPOP/N pins drive IEEE
802.3 compliant pulses onto the line.

TPIP
TPIN
I
Twisted-Pair Inputs, Positive and Negative.
During 100BASE-TX or 10BASE-T operation, TPIP/N pins receive
differential 100BASE-TX or 10BASE-T signals from the line.
