IAP1 (Input Accumulator from port P1)
1001100001
261
11
Grouping:
Input/Output operation
Description: Transfers the input of port P1 to register A.
Operation:
(A) ← (P1)
IAP2 (Input Accumulator from port P2)
1001100010
262
11
Grouping:
Input/Output operation
Description: Transfers the input of port P2 to the low-or-
der 2 bits (A1, A0) of register A.
Note:
After this instruction is executed, “0” is
stored to the high-order 2 bits (A3, A2) of
register A.
Operation:
(A1, A0) ← (P21, P20)
(A3, A2) ← 0

(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
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, “0” is
stored to the high-order 2 bits (A3, A2) of
register A.
Operation:
(A1, A0) ← (P31, P30)
(A3, A2) ← 0
