Programmable Interrupt Controller (PIC)

To change the vector, priority, polarity, sense, or destination of an active (unmasked) interrupt source, the

following steps should be taken:

Note that changing the destination from int to cint or IRQ_OUT makes the A, MSK, and PRIORITY fields

meaningless.

1. Mask the source using the mask (MSK) bit in the vector/priority register.

2. Wait for the activity (A) bit for that source to be cleared.

3. Make the desired changes.

4. Unmask the source.
