CHAPTER 6
Description
Parameters:
-
enFlt: network traffic/receive filter flags. Each bit corresponds to the appropri-
ate network traffic/receive filter:
Note: Advance filtering available in the
ENC28J60 module such as Pattern
Match, Magic Packet and Hash Table can not be enabled by this routine. Addi-
tionaly, all filters, except CRC, enabled with this routine will work in OR mode,
which means that packet will be received if any of the enabled filters accepts it.
Note: This routine will change receive filter configuration on-the-fly. It will not, in
any way, mess with enabling/disabling receive/transmit logic or any other part of
the
ENC28J60 module. The ENC28J60 module should be properly cofigured by
the means of Spi_Ethernet_Init routine.
Requires Ethernet module has to be initialized. See Spi_Ethernet_Init.
Example
Spi_Ethernet_Enable(Spi_Ethernet_CRC or Spi_Ethernet_UNICAST); //
enable CRC checking and Unicast traffic
