The following two figures diagram IEEE SMI read and IEEE SMI write operations.
13.3 SMI Interrupt
The SMI includes an output signal MDINT for signaling the Station Manager when certain events occur in the PHY. The MDINT
pin can be configured for active-low or active-high operation by tying the pin to either a pull-up resistor to VDDIOMICRO or to a
pull-down resistor to GND.
