With the three input types and six symbols, there are 18 different possible combinations.
The input comparison instruction
compares the data specified in S1 and S2
as single-precision floating point values
(32-bit IEEE754 data) and creates an ON
execution condition when the comparison
condition is true.
When the data is stored in words, S1 and
S2 specify the first of two words
containing the 32-bit data. It is also
possible to input the floating-point data as
an 8-digit hexadecimal constant.
The input comparison instructions are
treated just like the LD, AND, and OR
instructions to control the execution of
subsequent instructions.
LD: The instruction can be connected
directly to the left bus bar.
AND: The instruction cannot be
connected directly to the left bus bar.
OR: The instruction can be connected
directly to the left bus bar.
