PRODUCTION DATA
IEEE power-down switch disables all PHY circuitry except the SMI and internal clock circuitry.
IEEE power-down switch can be activated by either register access or through the INTR/PWRDN pin when the pin is configured for power-down function.
To enable IEEE power-down switch through the INTR/PWRDN pin, the pin must be driven LOW to ground.
To enable IEEE power-down switch through the SMI, set bit[11] = 1 in the BASIC mode Control Register (BMCR, address 0x0000).
