Operation:
(A3, A2) ← (AD1, AD0)
(A1, A0) ← 0
Grouping: A/D conversion operation
Description: Transfers the low-order 2 bits (AD1, AD0) of
register AD to the high-order 2 bits (A3, A2)
of register A.
Note:
After this instruction is executed, “0” is
stored to the low-order 2 bits (A1, A0) of
register A.
