PRODUCTION DATA
This is same as IEEE power down but the XI pad is also turned off. To enable this mode, the following sequence of register writes need to be performed.
If Deep Power Down Mode is activated through a register write, then clearing the power-down bit will bring the PHY back to normal mode. If the power-down mode is activate through PWDN pin assertion, then the PWDN pin must be deasserted followed by a valid Reset pulse to bring the PHY back to normal operation.
The Power Down Input pin is a shared pin which also acts an Interrupt Output pin. The nature of the pin can be changed through Register 0x1E bit[7]. When changing the pin from Interrupt Output to Power Down Input, the following sequence of register writes must be performed.
