Grouping:
Arithmetic operation
Description: Clears (0) to carry flag CY.
Operation:
(CY) ← 0
RTI (ReTurn from Interrupt)

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

Grouping:
Input/Output operation
Description: Clears (0) to a bit of port D specified by register Y.
Note:
(Y) = 0 to 5.
Do not execute this instruction if values ex-
cept above are set to register Y.
Operation:
(D(Y)) ← 0
However,
(Y) = 0 to 5
