Contents
Interrupt Input No.
0: Unit number 0 (interrupt tasks 100 to 115)
1: Unit number 1 (interrupt tasks 116 to 131)
0: Unit number 0 (interrupt tasks 100 to 107)
1: Unit number 1 (interrupt tasks 108 to 115)
2: Unit number 2 (interrupt tasks 116 to 123)
3: Unit number 3 (interrupt tasks 124 to 131)
6: Interrupt input 0 (interrupt task 140)
7: Interrupt input 1 (interrupt task 141)
8: Interrupt input 2 (interrupt task 142)
9: Interrupt input 3 (interrupt task 143)
Interrupt Mask
Set to 0000 to FFFF hex
Bits 0 to 15 correspond to each interrupt task. Individual bit settings are as follows:
0: Enable (unmask) the interrupt.
1: Disable (mask) the interrupt.
Set to 0000 to 00FF hex
Bits 0 to 7 correspond to each interrupt task. Individual bit settings are as follows:
0: Enable (unmasks) the interrupt.
1: Disable (masks) the interrupt.
0000 hex: Enable (unmask) the interrupt (direct mode).
0001 hex: Disable (mask) the interrupt (direct mode).
0002 hex: Start decrementing counter and enable interrupt (counter mode).
0003 hex: Start incrementing counter and enable interrupt (counter mode).
