terminalthe oval symbol show below in indicate terminal of the program usually words like start begin stop end
algorithm pseudo code and flow charts algorithm before writing the program the programmer must understand the
8085 is a one address microprocessorin 8085 interrupts are classified by hardware and software interupts
8085 the interrupts are classified as software and hardware
assembly language programming in this chapter we will discuss programming in assembly language and
indirect addressing in this addressing mo e also ne of the operands is the stored in the memory the memory address of the
direct addressing in this addressing mode one of the operands is the data stored in the memory the memory address of
immediate addressing in this addressing mode that 816 bit data is specified in the instruction itself as its one of
register addressing in this mode the operand are microprocessors registers only i e the operations is performed within
trap has the maximum prioritythere are 2 types of interrupts external and internal nmi has highest priority between all external interruptstrap has
addressing model as we have learned already that each instruction has two parts one is op code and another is operand op
the five addressing modes are given belowimmediateregisterdirectimplied addressing modes register
sub instruction op code format is of sub instruction isreplace the three bit code of the register r from to obtain the op
there are total 12 interrupts in 8085 there are total 12 interrupts in 8085
add instruction op code format of add instruction isreplace the three bit code of the register r from to obtain the op code
the maximum clock frequency for 8085 is 3
mov instructionop code format of mov instruction is as follows replace the codes of destination register and source register with
rst 45 is known as trap rst 45 is known as trap
op code format as we have seen in the section that the first byte of all the instruction is the op code microprocessors
flag is known as low order register amp accumulator is known as high order register
yes it can be used if an accurate clock frequency is not needed also the component cost is low contrast to lc or crystal
three byte instruction the instruction which have 16 bit data address as its operand are three byte instruction they
why address bus is unidirectional and data bus is bidirectionalans because there is no require address transaction among processor and peripheral
two byte instructions in these instruction the first byte specifies the operations code and the second byte specifies the
