CHAPTER 6
Requires Ethernet module has to be initialized. See SPI_Ethernet_Init.
Example
SPI_Ethernet_Enable(SPI_Ethernet_CRC | SPI_Ethernet_UNICAST); //
enable CRC checking and Unicast traffic
Prototype
void SPI_Ethernet_Disable(unsigned char disFlt) ;
Returns Nothing.
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, broad-
cast, 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 con-
stants (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:
Note: Advance filtering available in the
ENC28J60 module such as Pattern
Match
, Magic Packet and Hash Table can not be disabled by this routine.
