DP83867IR: WOL function

Part Number: DP83867IR

Hi

I have some question about WOL setting.

1, If we would like to set enable WOL, should we set "1" on MICR (MII interrupt control resister) [3]? 

   Is there any other setting should we set?

2, At RXFCFG(Recice configuration register), what is WOL_OUT_MODE?

   If we connect with i.MX6, which either should we set "0" or "1"?

Regards,

Koji Hamamoto

    Hi Koji-san,

    1. To enable WOL mode, set bit[7] in register 0x0134 to 1. Also set bits 4 through 0 in register 0x0134 as you need for the WOL mode you want.

    2. WOL_OUT_MODE changes the WOL GPIO pulse from a constant level that is only cleared after writing to the bit[11] of RXFCFG register. Or a pulse to wake up the MAC. This choice depends on the way your system handles the interrupt. A pulse mode is used most often.

    Best Regards,
