INR affect the carry flag.
Carry
There is no exit instruction in the 8085. Do you mean return, as in from a function or interrupt? If so, the instruction is RET.
Jump on Carry is simply a "JUMP" instruction which will transfer the control to some specific location if carry flag is set. For Example: JC 2004H This instruction will take the control to address location 2004H if carry flag is set.
The compare and subtract instructions in the 8085 both subtract one operand from another, and set flags accordingly. The subtract instruction stores the result in the accumulator, while the compare instruction does not - except for the flags, the compare instruction "throws" the result away.
Not in the 8085.
There are 74 instructions in the 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.
1. Memory Read - (PC) and then increment PC - Op Code C1 - Four clocks 2. Memory Read - (SP) and then increment SP - Transfer to C - Three clocks 3. Memory Read - (SP) and then increment SP - Transfer to B - Three clocks
MUL is not an 8085 instruction.
You can clear carry by using these two commands STC // it will force to set the carry flag CF=1// CMC //it willl complement that carry and you have done, CF=0 // in single instruction u can reset carry by using any logical instruction. because logical operation resets carry always... eg. XRI 00h or ANI 0F Geniusminds.com
CALL, requiring 18 clock cycles.
