5.4.8 Based indexed addressing
[Function]
[Operand format]
[Description example]
[Illustration]
The B or C register contents specified in an instruction word are added to the contents of the base register, that
is, the HL register pair in the register bank specified by the register bank select flags (RBS0 and RBS1) and the
sum is used to address the memory. Addition is performed by expanding the B or C register contents as a positive
number to 16 bits. A carry from the 16th bit is ignored. This addressing can be carried out for all the memory
spaces.
In the case of MOV A, [HL + B] (selecting the B register)
HL
The contents of the
memory addressed
