Description: The contents of the Index Register (register pair IY) is added to a two’s
Condition Bits Affected:
Example:
UM008005-0205
A ← A + (ID+d)
ADD
A, (IY + d)
complement displacement d to point to an address in memory. The contents
of this address is then added to the contents of the Accumulator, and the
result is stored in the Accumulator.
S is set if result is negative; reset otherwise
Z is set if result is zero; reset otherwise
H is set if carry from bit 3: reset otherwise
P/V is set if overflow; reset otherwise
N is reset
C is set if carry from bit 7; reset otherwise
