The power management (PMT) module supports the reception of network remote wake-up frames and AMD Magic Packet frames. The PMT module does not perform the clock gate function, but generates interrupts for remote wake-up frames and magic packets that the MAC receives.
When the application enables the power-down mode in the PMT module by setting the PWRDWN bit in the Ethernet MAC PMT Control and Status Register (EMACPMTCTLSTAT) register, MAC offset 0x02C, the MAC drops all received frames and does not forward any frame to the TX/RX Controller RxFIFO or the application. The MAC comes out of the power-down mode only when a magic packet or a remote wake-up frame is received and the corresponding detection is enabled.
