Notes: LAN WAKE-UP Signal (When CardB_En=0, bit2 Config3). This signal is used to inform the motherboard to execute the wake-up process. The motherboard must support Wake-On-LAN (WOL). There are 4 choices of output that may be asserted from the LANWAKE pin (active high, active low, positive pulse, and negative pulse). We can configure the LANWAKE output via two CONFIG bits: LWACT (Config1.4) and LWPTN (Config4.2). LWAKE Output LWACT 0 1 LWPTN 0 Active high Active low 1 Positive pulse Negative pulse The default output is an active high signal. Once a PME event is received, the LANWAKE and PMEB assert at the same time if the LWPME (bit4, CONFIG4) is set to 0. If the LWPME is set to 1, the LANWAKE asserts only when PMEB asserts and ISOLATEB is low
Ensure, WOL properly works upon bit-set. Need to test along several R8169 models including, R8169, R8169S, R8169S-32, R8169-64, R8169-SB, SB-LF, and SC
