Grouping:
Arithmetic operation
Description: Loads the value n in the immediate field to
register A.
When the LA instructions are continuously
coded and executed, only the first LA in-
struction is executed and other LA
instructions coded continuously are
skipped.
Operation:
(A)
← n

description
Grouping:
RAM addresses
Description: Loads the value x in the immediate field to
register X, and the value y in the immediate
field to register Y. When the LXY instruc-
tions are continuously coded and executed,
only the first LXY instruction is executed
and other LXY instructions coded continu-
ously are skipped.
Operation:
(X)
← x x = 0 to 15
(Y)
← y y = 0 to 15
