Tell me which registers are used for register indirect addressing mode if data is on-chip?
Answer:
☛ R0 and R1 are the only registers used for register indirect addressing mode.
☛ These registers are 8 bit wide.
☛ Their use is limited to accessing only internal RAM.
☛ When these registers hold addresses of RAM, they must be preceded by a @ sign.
☛ In absence of this sign it will use the contents of register than the contents of memory location pointed by the same register.
