The initial values (in hexadecimal format) of registers, R1, R2, R3, R4 and the arithmetic logic flags (C, N, V and Z) of a microprocessor are shown as below. Determine the contents of all the registers and ALU flags after the following operations. Please explain your answer and show your calculation steps. (a) (b) (c) ADD R1, R2, R3.
