1. The I bit in the condition code register is a global mask for all interrupt sources except the SWI instruction.
2. 0 = highest priority
Source
modifies the H register or uses the indexed addressing mode, save the H
register and then restore it prior to exiting the routine.
A software interrupt pushes PC onto the stack. An SWI does not push PC
– 1, as a hardware interrupt does.
