Arithmetic Operations
Various types of arithmetic operations like addition subtraction increment and decrement are performed in 8085 microprocessor. Generally in these operations one of the two operands is accumulator and result of operation is also stored in the accumulator except few exceptions. And after any arithmetic operation is performed flags are modified except few exceptions. Which flags are modified and which are not modified is specified with explanation of all instruction separately.
Readers are advised to see changes in the flag after each operations carefully.
