Interrupt Control Instructions Section 3-20
Specifying I/O Interrupt Processing Rising/Falling Edge Designation
The relationship between Interrupt Input Unit unit numbers and interrupt task
numbers is shown in the following table.
Note All interrupt inputs that have been detected will be cleared when the rising/fall-
ing edge designation is changed.
C200HS-INT01
Specifying I/O Interrupt Processing and Mask Processing
Note 1. The CS1W-INT01 and the C200HS-INT01 cannot be used at the same
time.
2. All interrupt inputs that have been detected will be cleared when the inter-
rupt mask is cleared.
The relationship between Interrupt Input Unit unit numbers and interrupt task
numbers is shown in the following table.
Note All interrupt inputs that have been detected will be cleared when the rising/fall-
ing edge designation is changed.
Operand Contents
N Specify the Interrupt Input Unit’s unit number.
2: Unit number 0
3: Unit number 1
S Specify either the rising or falling edge of the interrupt input sig-
nal.
Set to 0000 to FFFF Hex (16 bits per Unit).
Individual bits indicate the following:
0: Rising edge
1: Falling edge
Unit
number
Interrupt task numbers
2 100 to 115 Bits 00 to 15 of S correspond to the input interrupt
tasks.

Unit
number
Interrupt task numbers
0 100 to 107 Bits 00 to 07 of S correspond to the input interrupt
tasks.
