REGISTER COMPARISON TABLE: CTBL(882) Section 5-4
For range comparison, the comparison table always contains eight ranges.
The table is 40 words long, as shown below. If it is not necessary to set eight
ranges, set the interrupt task number to FFFF hex for all unused ranges.
Note Always set the upper limit greater than or equal to the lower limit for any one
range.
Operand Specifications
Description CTBL(882) registers a comparison table or registers and comparison table
and starts comparison for the port specified in P and the method specified in
