Explain register direct and indirect data addressing mode, Electrical Engineering

Assignment Help:

Explain Register Direct and Indirect data addressing mode (with examples) available in microprocessors.

Register Direct Modes and Register Indirect Modes:

Does not give a memory address. Instead give a register.

Illustration:

LDAC R

Here R is a register having the value 5.The instruction copies this value 5 from register and in the CPU's accumulator.
