5-19-6 SIGNED BINARY COMPARE – CPS(––)
Description
286
ER: One of the tables (i.e., TB1 through TB1+15, or TB2 through TB2+15)
exceeds the data area.
Indirectly addressed EM/DM word is non-existent.
(Content of *EM/*DM word is not BCD, or the EM/DM area boundary
has been exceeded.)
EQ: ON if the entire contents of both tables are equal and R=0000.
The following example shows the comparisons made and the results provided
for MCMP(19). Here, the comparison is made during each cycle when 00000
is ON.

When the execution condition is OFF, CPS(––) is not executed. When the exe-
cution condition is ON, CPS(––) compares the 16-bit (4-digit) signed binary
contents in Cp1 and Cp2 and outputs the result to the GR, EQ, and LE flags in
the SR area.
