Symbol comparison instructions (unsigned) compare two values
(constants and/or the contents of specified words) in 16-bit binary
data and create an ON execution condition when the comparison

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 com-
parison condition is true. There are three types of symbol comparison
instructions, LD (LOAD), AND, and OR.
Function
ON execution condition when
comparison result is true.
ON execution condition
when comparison result
is true.
