Grouping:
Return operation
Description: Returns from interrupt service routine to
main routine.
Returns each value of data pointer (X, Y, Z),
carry flag, skip status, NOP mode status by
the continuous description of the LA/LXY in-
struction, register A and register B to the
states just before interrupt.
Operation:
(PC) ← (SK(SP))
(SP) ← (SP) – 1
RT (ReTurn from subroutine)

12
Grouping:
Return operation
Description: Returns from subroutine to the routine
called the subroutine.
Operation:
(PC) ← (SK(SP))
(SP) ← (SP) – 1
RTS (ReTurn from subroutine and Skip)
0001000101

Skip at uncondition
Grouping:
Return operation
Description: Returns from subroutine to the routine
called the subroutine, and skips the next in-
struction at uncondition.
Operation:
(PC) ← (SK(SP))
(SP) ← (SP) – 1

Grouping:
Other operation
Description: Clears (0) to the high-order bit reference
enable flag UPTF.
