MI - Mask Interrupt
Purpose:
Selects which interrupts (automatic routines) are active.
A user program may include a main code section and some automatic routines. When
the program runs, the conditions for calling these routines are checked continuously.
If the conditions for running an automatic routine
3
are met, it is called. At certain
times, you may want to block some of the automatic routines. For example:
 An #@AUTO_RLS automatic routine may be deactivated in a homing process.
 You may want a certain code sequence to be non-interruptible.
 Certain auto-routines may be needed only when starting the program from
certain labels.
MI is a bit field. Each bit in MI masks its corresponding automatic routine, preventing
its execution. The MI bits are detailed in the following table:
MI Value Masked Interrupt Relevant Routine
1 (0x1) Not used 0
2 (0x2) Abort AUTO_ER
4 (0x4) Soft stop AUTO_STOP
8 (0x8) Soft begin AUTO_BG
16 (0x10) RLS AUTO_RLS
32 (0x20) FLS AUTO_FLS
64 (0x40) Switch enable AUTO_ENA
128 (0x80) Digital input 1 AUTO_I1
256 (0x100) Digital input 2 AUTO_I2
512 (0x200) Digital input 3 AUTO_I3
1024 (0x400) Digital input 4 AUTO_I4
2048 (0x800) Digital input 5 AUTO_I5
4096 (0x1000) Digital input 6 AUTO_I6
8192 (0x2000) Main home event AUTO_HM
16,384 (0x4000) Auxiliary home event AUTO_HY
32,768 (0x8000) User program error AUTO_PERR

These conditions include the requirements that no interrupt request of high priority is
pending (in which case the corresponding automatic routine enters the pending list) and
that the interrupt is not masked (in which case the interrupt is ignored).
