179 / 329 page  2015 Microchip Technology Inc. DS00001909A-page 179 LAN9252 11.2.16.25 PHY x Wakeup Control and Status Register (PHY_WUCSR_x) Note 17: Register bits designated as NASR are reset when the PHY Reset is generated via the Reset Control Reg- ister (RESET_CTL). The NASR designation is only applicable when the Soft Reset (PHY_SRST) bit of the PHY x Basic Control Register (PHY_BASIC_CONTROL_x) is set. Index (In Decimal): 3.32784 Size: 16 bits Bits Description Type Default 15:9 RESERVED RO - 8 WoL Configured This bit may be set by software after the WoL registers are configured. This sticky bit (and all other WoL related register bits) is reset only via a power cycle or a pin reset, allowing software to skip programming of the WoL regis- ters in response to a WoL event. Note: Refer to Section 11.2.9, "Wake on LAN (WoL)," on page 132 for additional information. R/W/ NASR Note 17 0b 7 Perfect DA Frame Received (PFDA_FR) The MAC sets this bit upon receiving a valid frame with a destination address that matches the physical address. R/WC/ NASR Note 17 0b 6 Remote Wakeup Frame Received (WUFR) The MAC sets this bit upon receiving a valid remote Wakeup Frame. R/WC/ NASR Note 17 0b 5 Magic Packet Received (MPR) The MAC sets this bit upon receiving a valid Magic Packet. R/WC/ NASR Note 17 0b 4 Broadcast Frame Received (BCAST_FR) The MAC Sets this bit upon receiving a valid broadcast frame. R/WC/ NASR Note 17 0b 3 Perfect DA Wakeup Enable (PFDA_EN) When set, remote wakeup mode is enabled and the MAC is capable of wak- ing up on receipt of a frame with a destination address that matches the physical address of the device. The physical address is stored in the PHY x MAC Receive Address A Register (PHY_RX_ADDRA_x), PHY x MAC Receive Address B Register (PHY_RX_ADDRB_x) and PHY x MAC Receive Address C Register (PHY_RX_ADDRC_x). R/W/ NASR Note 17 0b 2 Wakeup Frame Enable (WUEN) When set, remote wakeup mode is enabled and the MAC is capable of detecting Wakeup Frames as programmed in the Wakeup Filter. R/W/ NASR Note 17 0b 1 Magic Packet Enable (MPEN) When set, Magic Packet wakeup mode is enabled. R/W/ NASR Note 17 0b 0 Broadcast Wakeup Enable (BCST_EN) When set, remote wakeup mode is enabled and the MAC is capable of wak- ing up from a broadcast frame. R/W/ NASR Note 17 0b |
