With interrupt inputs in counter mode, the subroutine to be executed is deter-
mined by the interrupt corresponding to the input number.
Input number

00004
00005*
00006*
Note *Input numbers 00005 and 00006 cannot be used for CPM2C CPU Units with 10
I/O points and for CPM2C-S CPU Units.
The same input number (from 00003 to 00006) cannot be used for more than
one of the following functions: interrupt inputs, interrupt inputs (counter mode),
or quick-response inputs.
