WebApr 1, 2024 · It is an 8-bit register that contains 8 flip-flops. It can store a maximum of 8 bits of data. The importance of the accumulator is that, in most of the 8-bit arithmetic and logical operations, the microprocessor will always take the first 8-bit number from the accumulator. Temporary Registers: There are three 8-bit registers W, X, and Z. WebThe DAA (Decimal Adjust Accumulator) instruction also works on the data of AL register. This instruction does not need any operand. This instruction is used to convert the sum of two packed BCD numbers into a valid BCD number. It checks the AL data and performs the following operations: 1. If lower nibble of AL > 9 or AF=1 then:
