User Interrupts Appendix D
For example, to enable EII Event 1 and EII Event 3:
EII Event 1 = 4, EII Event 3 = 16
4 + 16 = 20 (enter this value)
UIF - User Interrupt Flush
The UIF instruction is used to flush (remove pending interrupts from the
system) selected user interrupts. The table below shows the types of interrupts
with their corresponding flush bits:
To flush interrupt(s):
1. Select which interrupts you want to flush.
