Explain briefly the flag register in the 8085 microprocessor. - The flag register in 8085 is an 8-bit register which contains 5 bit positions. - These five flags are of 1bit F/F and are known as zero, sign, carry, parity and auxiliary carry. - For sign flag if the result of an MS...
8085flag bitsIn comparing two signed operands, it may be shown theoretically that, if operand 1 is greater than operand 2, then flag bit X5 is reset; otherwise X5 is set. In this paper, JX5 and JNX5 instructions are used for checking the set and reset conditions, respectively, of X5 ...
In this tutorial, we will learn how to access and exchange the content of flag register F with register B in 8085 Microprocessor? By Ayush Sharma Last updated : May 13, 2023 8085 program to access and exchange the content of Flag register with re...
regular register), in memory, in a unique indicator (i.e. a flags register), or in a shared condition register (e.g. System/360). The point is that while the typical microprocessor approach of storing flags in a flag register may seem natural, many alternatives have been tried in ...

By making use of the Push & Pop instructions the program can be written as: - LXISP, 4000H - this step initiates the SP at 4000h. -PUSH PSW - the contents of the accumulator and flag are pushed into the stack. - POP B - MOV A, B ...
