3.4.7 Based addressing
[Function]
[Operand format]
[Description example]
[Illustration]
8-bit immediate data is added as offset data to the contents of the base register, that is, the HL register pair in
the register bank specified by the register bank select flag (RBS0 and RBS1), and the sum is used to address
the memory. Addition is performed by expanding the offset data 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.
