Appendix D User Interrupts
EII User Interrupt Pending (EII0.PE)
PE (User Interrupt Pending) is a status flag that represents an interrupt is
pending. This status bit can be monitored, or used for logic purposes, in the
control program if you need to determine when a subroutine cannot execute
immediately.
This bit is automatically set and cleared by the controller. The controller can
process 1 active and maintain up to 1 pending user interrupt conditions before it
sets the lost bit.
