Example of enabling the execution of interrupt programs
Example:
ICTL, H0, H101DF
S1
S2
[S1]: H0000
This specifies whether execution of the interrupt program
corresponding to the interrupt from the interrupt unit (INT0 to
INT15) is enabled or disabled.
[S2]: H0101
Enable INT0 and INT8 (set bits 0 and 8 to “1”) and disable all
others.

Set the bits to “1” that correspond to the interrupts to be
enabled.
The I/O number is an example showing the interrupt unit
mounted in Slot 0.
To enable all interrupts INT0 to INT15, set S2 = HFFFF.
