Interrupt Functions
Section 6-1
REGISTER
COMPARISON TABLE
Instruction:
CTBL(882)
CTBL(882) compares the PV of a high-speed counter (0 to 3) to target values
or target value ranges and executes the corresponding interrupt task (0 to
255) when the specified condition is met.
Contents of the
Comparison Table
Target-value Comparison Table
Depending on the number of target values in the table, the target-value com-
parison table requires a continuous block of 4 to 145 words.
Range Comparison Table
The range comparison table requires a continuous block of 40 words because
comparison conditions 1 to 8 require 5 words each (2 words for the upper
range value, 2 words for the lower range value, and one word for the interrupt
task number).
