SPI_Ethernet_Disable

sub procedure SPI_Ethernet_Disable(dim disFlt as byte)

Description This is MAC module routine. This routine disables appropriate network traffic on the 

ENC28J60

 module 

by the means of it’s receive filters (unicast, multicast, broadcast, crc). Specific type of network traffic 

will be disabled if a corresponding bit of this routine’s input parameter is set. Therefore, more than one 

type of network traffic can be disabled at the same time. For this purpose, predefined library constants 

(see the table below) can be ORed to form appropriate input value. 

Parameters - 

disFlt

: network traffic/receive filter flags. Each bit corresponds to the appropriate network traffic/

receive filter: 

Nothing.

Ethernet module has to be initialized. See SPI_Ethernet_Init.

SPI_Ethernet_Disable(_SPI_Ethernet_CRC or _SPI_Ethernet_UNICAST) ‘ disable 

Advanced filtering available in the 

ENC28J60

 module such as 

Pattern Match, Magic Packet 

and

 Hash Table

 can not be disabled by this routine.

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.
