What is the purpose of adc instruction according to 8085 microprocessor?
this instruction is used to add the specified register content to that of the accumulator along with the carry flag value. this instruction is used in processes which involve continuous addition.
What is the use of debug in 8086 microprocessor?
The debug flag in the 8086/8088 microprocessor causes one instruction to be executed, followed immediately by a debug interrupt. The flag then gets turned off, so you get get nested debug interrupts. This is used by a debugger program to single step a process that it is debugging (the debugee, so to speak).
Which flag bit controls INTR pin on the microprocessor?
I flag
What is the importance of flags in microprocessor?
sign flag parity flag zero flag
What is compare instruction 8086 microprocessor?
the compare instruction of 808 is used to compare the 2 operands. syntax: cmp op1,op2 algorithm: op1-op2 the value of the operands are not affected only the flags are updated if op1<op2 carry=1 and zero flag=0 if op1=op2 cy=0 and zf=1 if op1>op2 cy=0 and zf=0
Which group of instruction do not effect the flag?
(a) Arithmetic operations (b) Logic operations (c) Data transfer operations (d) Branch operations
Will DCX instruction affect the zero flag?
no....it does not aff
Why increment INR instruction in 8085 does not affect carry flag?
INR affect the carry flag.
When did Flag Group end?
Flag Group ended in 1990.
When was Flag Group created?
Flag Group was created in 1986.
What is a flag in micro processor?
Flags are kind of register that record the condition of a microprocessor's calculation process.
What is the use of direction flag and Trace flag in 8086?
The direction flag (DF) controls the direction of repeated string instructions. The trap flag (TF) executes one instruction and then executes a debug (INT 1) instruction so that a debugger can single step through a program.
