Let me know, if is there any logic behind that?</SPAN><BR /><BR /><BR /><SPAN>Thanks and regards,</SPAN><BR /><BR /><SPAN>Krishnakumar Kulkarni</SPAN><BR /></BODY></HTML> Wed, 15 Jun 2016 18:37:42 GMT lpcware 2016-06-15T18:37:42Z LPC4330 ethernet- remote wake up frame filter. https://community.nxp.com/t5/LPC-Microcontrollers/LPC4330-ethernet-remote-wake-up-frame-filter/m-p/553268#M14531 <HTML><HEAD></HEAD><BODY><STRONG>Content originally posted in LPCWare by Krishnakumar on Mon Sep 29 04:38:21 MST 2014</STRONG><BR /><SPAN>Hi folks,</SPAN><BR /><BR /><SPAN>In LPC4330 ethernet, It has a register called remote wake up frame filter(WAKEUPFMFILTER_REG) which is used for wake on lan configuration by wake up farme.</SPAN><BR /><BR /><SPAN>The WAKEUPFMFILTER has a field called "filter i CRC_16" which is 16 bits wide.
