18.8.5
The Pattern Match filter selects up to 64 bytes from the
incoming packet and calculates an IP checksum of the
bytes. The checksum is then compared to the EPMCS
registers. The packet meets the Pattern Match filter cri-
teria if the calculated checksum matches the EPMCS
registers. The Pattern Match filter may be useful for
filtering packets which have expected data inside them.
To use the Pattern Match filter, the application must
program the Pattern Match offset (EPMOH:EPMOL),
all of the Pattern Match mask bytes (EPMM0:EPMM7)
and the Pattern Match Checksum register pair
(EPMCSH:EPMCSL). The Pattern Match offset should
be loaded with the offset from the beginning of the des-
tination address field to the 64-byte window which will
be used for the checksum computation. Within the
64-byte window, each individual byte can be selectively
included or excluded from the checksum computation
by setting or clearing the respective bit in the Pattern
Match mask. If a packet is received which would cause
the 64 byte window to extend past the end of the CRC,
the filter criteria will immediately not be met, even if the
corresponding mask bits are all ‘0’.

PATTERN MATCH FILTER
In all cases, the value of the Pattern Match
offset must be even for proper operation.
Programming the EMPO register pair with
an odd value will cause unpredictable
results.

The Pattern Match Checksum registers should be
programmed to the checksum which is expected for the
selected bytes. The checksum is calculated in the
same manner that the DMA module calculates
checksums (see Section 18.9.2 “Checksum Calcula-
tions”). Data bytes which have corresponding mask
bits programmed to ‘0’ are completely removed for
purposes of calculating the checksum, as opposed to
treating the data bytes as zero.
As an example, if the application wished to filter all
packets having a particular source MAC address of
00-04-A3-FF-FF-FF, it could program the Pattern
Match offset to 0000h and then set bits 6 and 7 of
EPMM0 and bits 0, 1, 2 and 3 of EPMM1 (assuming all
other mask bits are ‘0’). The proper checksum to pro-
gram into the EPMCS registers would be 5BFCh. As an
alternative configuration, it could program the offset to
0006h and set bits 0, 1, 2, 3, 4 and 5 of EPMM0. The
checksum would still be 5BFCh. However, the second
case would be less desirable as packets less than
70 bytes long could never meet the Pattern Match cri-
teria, even if they would generate the proper checksum
given the mask configuration.
Another example of a Pattern Match filter is illustrated
in Figure 18-14.
