Description
250
The following example shows the comparisons made and the results provided
for TCMP(85). Here, the comparison is made during each cycle when IR
00000 is ON.
Upper limits
DM 0000 0100
DM 0001 0200
DM 0002 0210
DM 0003 0400
DM 0004 0500
DM 0005 0600
DM 0006 0210
DM 0007 0800
DM 0008 0900
DM 0009 1000
DM 0010 0210
DM 0011 1200
DM 0012 1300
DM 0013 1400

Note BCMP(68) is an expansion instruction for the SRM1. The function code 68 is
the factory setting and can be changed for the SRM1 if desired.
Each lower limit word in the comparison block must be less than or equal to
the upper limit.
DM 6144 to DM 6655 cannot be used for R.
When the execution condition is OFF, BCMP(68) is not executed. When the
execution condition is ON, BCMP(68) compares CD to the ranges defined by
a block consisting of CB, CB+1, CB+2, ..., CB+31. Each range is defined by
two words, the first one providing the lower limit and the second word provid-
ing the upper limit. If CD is found to be within any of these ranges (inclusive of
the upper and lower limits), the corresponding bit in R is set. The comparisons
