4.0 Register Set (Continued)

Example: Pattern match on the following destination addresses:

02-00-03-01-04-02

12-10-13-11-14-12

22-20-23-21-24-22

32-30-33-31-34-32

set $PATBUF01 = 280

set $PATBUF23 = 300

# write counts

iow l $RFCR (0006)

# pattern count registers 1, 0

iow l $RFDR (0406)

# count 1 = 4, count 0= 6

iow l $RFCR (0008)

# pattern count registers 3, 2

iow l $RFDR (0406)

# count 3 = 4, count 2 = 6

# write data pattern into buffer 0

iow l $RFCR ($PATBUF01)

iow l $RFDR (0002)

iow l $RFCR ($PATBUF01 + 4)

iow l $RFDR (0103)

iow l $RFCR ($PATBUF01 + 8)

iow l $RFDR (0204)

# write data pattern into buffer 1

iow l $RFCR ($PATBUF01 + 2)

iow l $RFDR (1012)

iow l $RFCR ($PATBUF01 + 6)

iow l $RFDR (1113)

iow l $RFCR ($PATBUF01 + a)

iow l $RFDR (1214)

# write data pattern into buffer 2

iow l $RFCR ($PATBUF23)

iow l $RFDR (2022)

iow l $RFCR ($PATBUF23 + 4)

iow l $RFDR (2123)

iow l $RFCR ($PATBUF23 + 8)

iow l $RFDR (2224)

# write data pattern into buffer 3

iow l $RFCR ($PATBUF23 +2)

iow l $RFDR (3032)

iow l $RFCR ($PATBUF23 + 6)

iow l $RFDR (3133)

iow l $RFCR ($PATBUF23 + a)

iow l $RFDR (3234)

#enable receive filter on all patterns

iow l $RFCR ($RFEN|$APAT0|$APAT1|$APAT2|$APAT3)

Example of how to mask out a byte in a pattern:

# write data pattern into buffer 0

iow l $RFCR ($PATBUF01)

iow l $RFDR (10002)

#mask byte 0 (value = 02)

iow l $RFCR ($PATBUF01 + 4)

iow l $RFDR (20103)

#mask byte 1 (value = 01)

iow l $RFCR ($PATBUF01 + 8)

iow l $RFDR (30204)

#mask byte 0 and 1
