013
11
(Y) = 0
Grouping:
RAM addresses
Description: Adds 1 to the contents of register Y. As a re-
sult of addition, when the contents of
register Y is 0, the next instruction is
skipped. When the contents of register Y is
not 0, the next instruction is executed.
Operation:
(Y)
← (Y) + 1
LA n (Load n in Accumulator)
000111nnnn

Continuous
description
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
n = 0 to 15

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
IAP3 (Input Accumulator from port P3)
1001100011
263
11
Grouping:
Input/Output operation
Description: Transfers the input of port P3 to the low-or-
der 2 bits (A1, A0) of register A.
Note:
After this instruction is executed, sets “0” to
the high-order 2 bits (A3, A2) of register A.
Operation:
(A1, A0)
← (P31, P30)
(A3, A2)
← 0
