Filtering by IP4 and setting the
external output
Example: You want to filter by protocol type IPv4 and set the external output if a
frame with protocol type IPv4 arrives.
Protocol type IPv4 corresponds to 0x0800.
Set the following filter registers:
Register Parameter Function
SegFilter1:
x07 00 00 00 03 Word offset of protocol type
x08 00 00 00 08 IPv4 protocol type
x09 00 00 FF FF Mask on 2 bytes
Filter 1
x55 00 00 00 00 No negation of SegFilter1
x56 00 00 00 01 Filter1 consists of SegFilter1
Uplink
x65 00 00 00 00 Do not invert output
x66 00 00 00 00 Frame is output at the uplink port if filter 1 applies.
External output
x67 00 00 00 00 No negation of ext. out
x68 00 00 00 01 Set external output if filter 1 applies
ConfigReg
401 xx xx xx xE Activate filter for CON A port (1110)
extOut_ConfigReg
402 00 00 01 01 Port Con A active, reset via a timer
extOutTimerReg
403 01 31 2D 00 Timer resets the value every 200 ms
Filtering by CRC error
Example: You want to filter all frames that report a CRC error.
Set the following filter registers:
Register Parameter Function
State:
x05 08 00 00 00 CRC Error Statusbit
x06 FF 00 00 00 Mask on 1 byte
Filter 1
x55 00 00 00 00 No negation of StateFilter
x56 80 00 00 00 Filter1 consists of state filter
Uplink
x65 00 00 00 00 Do not invert output
x66 00 00 00 01 Frame is output at the uplink port if filter 1 applies.
ConfigReg
401 xx xx xx xE Activate filter for CON A port (1110)
