A <- A - (IX+d)
The contents of the Index (register pair IX) Register is added to a two's complement displacement d to point to an address in memory. The contents of this memory address are compared to the contents of the Accumulator. If there is a true compare, the Z flag is set. The execution of this instruction does not affect the contents of the Accumulator.
|S||is set if result is negative, otherwise it is reset.|
|Z||is set if result is 0, otherwise it is reset.|
|H||is set if borrow from bit4, otherwise it is reset.|
|P/V||is set if overflow, otherwise it is reset|
|C||is set if borrow, otherwise it is reset.|
If the Accumulator contains $63, Index Register IX contains $1000, and memory location $1005 contains $60, then upon the execution of
the P/V flag in the F Register is reset.
