2.2.1 Magic Packet Detection - Implementation

WoL Magic Packet detection requires use of the following registers:

Table 2-2 Magic Packet Detection Registers
Register Name DP8382x Address DP8386x Address
Receive Configuration Register Reg 0x4A0 Reg 0x134
Receive Status Register Reg 0x4A1 Reg 0x135
MAC Destination Address Registers Reg 0x4A2-0x4A4 Reg 0x136-0x138
Note:

While these registers are common to the DP8382x and DP8386x families, please consult PHY's individual data sheet for configuring specific GPIO pins for WoL with registers.

Examples Table 2-8 and Table 2-4 are intended to display various configuration options for DP8382x WoL Magic Packet detection feature.

Note:

For all examples below, the first byte (0) as listed in data sheet is the left-most byte. IE if pattern is "A1-C3-D7-AB-CD-FC-87", the first byte is A1, not 87.
