Outline of operation
● This instruction recovers 15 data (30 words) for the index register value, starting with [S].
([S] to [S] + 29) → (I0 to IE)
● The POPIX instruction is used to recover the content that has been backed up using the
PUSHIX (Index Register Backup) instruction, before switching from the subprogram to the
main program, in the case where index registers are used in subroutines or other
subprograms.
● Please use this in combination with the PUSHIX (Index Register Backup) instruction.
