MDC to the next rising edge of MDC. When data is being written to the PHY, it must be
valid around the rising edge of MDC.
Idle The sequence is repeated.
SMI Interrupts
The SMI also includes an output interrupt signal, MDINT, for signaling the station
manager when certain events occur in the PHY.
The MDINT pin can be configured for open-drain (active-low) by tying the pin to a
pull-up resistor and to VDDIO. The following illustration shows this configuration.
MDINT Configured as an Open-Drain (Active-Low) Pin
Alternatively, each MDINT pin can be configured for open-source (active-high) by tying
the pin to a pull-down resistor and to VSS. The following illustration shows this
configuration.
MDINT Configured as an Open-Source (Active-High) Pin
When a PHY generates an interrupt, the MDINT pin is asserted (driven high or low,
depending on resistor connection) if the interrupt pin enable bit (MII Register 25.15) is
set.
