Symbol comparison instructions (unsigned) compare two values
(constants and/or the contents of specified words) in 16-bit binary
S data and create an ON execution condition when the comparison
1
condition is true. There are three types of symbol comparison

instructions, LD (LOAD), AND, and OR.

Symbol comparison instructions (double-word, unsigned) compare two
values (constants and/or the contents of specified double-word data) in
unsigned 32-bit binary data and create an ON execution condition when
the comparison condition is true. There are three types of symbol com-
parison instructions, LD (LOAD), AND, and OR.
Symbol comparison instructions (signed) compare two values (con-
stants and/or the contents of specified words) in signed 16-bit binary (4-
digit hexadecimal) and create an ON execution condition when the
comparison condition is true. There are three types of symbol compari-
son instructions, LD (LOAD), AND, and OR.
Function
ON execution condition when
comparison result is true.
ON execution condition
when comparison result
is true.
<
ON execution condition when
comparison result is true.
