2.2.3 Custom Pattern Detection - Implementation

WoL Custom Pattern detection requires use of the following registers:

Table 2-9 Custom Pattern Detection Registers
Register Name DP83822 Address DP8386x Address
Receive Configuration Register Reg 0x4A0 Reg 0x134
Receive Status Register Reg 0x4A1 Reg 0x135
Pattern Matching Registers Reg 0x4A8-0x4C7 Reg 0x13C - 0x15B
Byte Mask Reg 0x4C8 - 0x4CB Reg 0x15C - 0x15F
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.

Table 2-11 and Table 2-11 intended to display configuration options for DP838xx WoL Custom Pattern detection with byte masking.
