IAK (Input Accumulator from port K)
1001101111
26F
11
Grouping:
Input/Output operation
Description: Transfers the contents of port K to the bit 0
(A0) of register A.
Note:
After this instruction is executed, “0” is
stored to the high-order 3 bits (A3–A1) of
register A.
Operation:
(A0)
← (K)
(A3–A1)
← 0

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 reg-
ister A.
Operation:
(A1, A0)
← (P21, P20)
(A3, A2)
← 0
Operation:
(A)
← (P0)
