Instruction Meaning
(@)CTBL(63) Used to register target or range comparison tables or to start comparisons for previously registered
comparison tables.
(@)INI(61) Used to start or stop comparison using registered comparison table or to change the PV of a high-
speed counter.
(@)PRV(62) Used to read the PV or status of a high-speed counter.
(@)INT(89) Used to perform mask all interrupts, such as input interrupts, interval timer interrupts, and high-speed
counter interrupts.
Word Bits Name Function

Flags
ON when counter PV satisfies con-
ditions for comparison range 1
When using high-speed counter 1 in
range comparison mode, each bit
turns ON when the corresponding
condition is satisfied.
01 ON when counter PV satisfies con-
ditions for comparison range 2
02 ON when counter PV satisfies con-
ditions for comparison range 3
03 ON when counter PV satisfies con-
ditions for comparison range 4
04 ON when counter PV satisfies con-
ditions for comparison range 5
05 ON when counter PV satisfies con-
ditions for comparison range 6
06 ON when counter PV satisfies con-
ditions for comparison range 7
07 ON when counter PV satisfies con-
ditions for comparison range 8
08 High-speed
Counter
Comparison
Flag
Indicates status of comparison operation.
