Port 1 & 2 PHY Power Management
The Port 1 & 2 PHYs provide independent general power-down and energy-detect power-down modes
which reduce PHY power consumption. General power-down mode provides power savings by
powering down the entire PHY, except the PHY management control interface. General power-down
mode must be manually enabled and disabled as described in
Down," on page
In energy-detect power-down mode, the PHY will resume from power-down when energy is seen on
the cable (typically from link pulses). If the ENERGYON interrupt (INT7) of either PHYs
Interrupt Mask Register (PHY_INTERRUPT_MASK_x)
generate an interrupt. These interrupts are reflected in the
(PHY_INT2) for the Port 2 PHY, and bit 26 (PHY_INT1) for the Port 1 PHY. These interrupts can be
used to trigger the IRQ interrupt output pin, as described in
on page
