Description

A is summed with the data whose address is in HL. The result is stored in A. The Rabbit 4000/5000 assemblers view "ADD A,(HL)" and "ADC (HL)" as equivalent instructions. In the latter case, A is used even though it is not explicitly stated.

The opcode for this instruction is different than the same instruction in the Rabbit 2000, 3000 and 3000A.
