Note: Bit 15 must be set to zero
To flush interrupt(s):
1. Select which interrupts you want to flush.
2. Find the Decimal Value for the interrupt(s) you selected.
3. Add the Decimal Values if you selected more than one type of
interrupt.
4. Enter the sum into the UIF instruction.
For example, to disable EII Event 1 and EII Event 3:
EII Event 1 = 32, EII Event 3 = 4
32 + 4 = 36 (enter this value)
