SPI_Ethernet_24j600_Disable

sub procedure SPI_Ethernet_24j600_Disable(dim disFlt as word)

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

ENC24J600 

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_24j600_Init.

Ethernet_24j600_UNICAST) ‘ disable CRC checking and Unicast traffic

Advanced filtering available in the 

ENC24J600

 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 

ENC24J600

 module. The 

ENC24J600

 module 

should be properly cofigured by the means of SPI_Ethernet_24j600_Init routine.

The 

ENC24J600

  module  should  be  properly  cofigured  by  the  means  of  SPI_Ethernet_24j600_Init 

routine.
