Initialization:
Instruction:
Result:
This example uses one word of memory and executes in one machine cycle. The operand
referenced by P2:1 is subtracted from the accumulator. 7A2500H - 546300H =
25C200H. Because the comparison does not yield a 0, Bit 0 is not set. The content of the
P2:1 register is appended with eight additional 0 bits. For consistent comparisons, the
accumulator must contain zeros in the lower eight bits.
Initialization:
Instruction:
Result:
This example uses one word of memory and executes in three machine cycles.The pointer
P2:1 contains the RAM register location (A4H). The contents of this register have a
ROM address. This address refers to the ROM data compared to the accumulator
7A2500H - OC1200H = 6E1300H. Because the comparison does not yield a 0, Bit 0
is not set. With memory indirect addressing, the ROM address is automatically
incremented. Using CP A,@@P2:1 + performs the same operation and also increments
P2:1 content to A5H.
