What is the largest hex value that can move into a 16-bit register?

In unsigned notation, 0xFFFF (65,535 decimal) is the largest value that will fit in a 16-bit register. In signed notation, 0x7FFF (32,767 decimal) is the largest because the most-significant bit denotes the sign.

∙ 11y agoThe largest 8-bit hex value is 0xFF which is 255 decimal. However, if the value is a signed value, 0xFF is -1 decimal. Thus the largest signed value would be 0x7F (127 decimal) while the smallest is 0x80 (-128).

MOV D IN Microprocessor means?
MOV D,reg means: move content of the specified register (or M=memory addressed with HL) into register D
Can the program counter be eliminated by using the top of the stack as a program count?
No. The program counter must be stored in a dedicated register. The stack is in working memory and you cannot operate on working memory; all values must be moved into a register in order to operate upon them. It makes no sense to move a program counter in and out of memory unless performing a context switch and you can't use a stack for context switching; a priority queue must be used for this. Keep in mind that the address of the top of the stack has to be moved in and out of its register during a context switch. It doesn't make sense to load the stack register from a priority queue before you can determine where the program counter value is. It's easier to keep all state information in the same place in the priority queue where it belongs.
What is the Structure of Program in Assembly language?
Assembly language programs are the Low level programs. We write Assembly Language program in basically 8085 and 8086 microprocessors.We can have several registers to do opreations with. Accumulator is one most important Register in a assembly program.We use several instructions like..Arithmetic:INR - Increment AccumulatorADD B - Add Content of Reg. B with AccumulatorSUB, etc.Logical:AND - Bitwise ANDJump Instriction:JZ label - Jump to label if ZERO flaggedJC Label - Jump on CarryEtc..
Assembly language pgm to find sum of n numbers?
C100 LXI H C200 21 ; Load the HL register pair immediately C101 00 ; C102 C2 ; C103 MOV B M 46 ; Move the memory content (Total number of data) in to B register C104 MVI C 00 0E ; Initialize the C register with 00 H C 105 00 ; C106 SUB A 97 ; Clear the ac cumulator C107 INX H 23 ; Increment the HL register pair (to get the next input data) C108 MOV A M 7E ; Move the memory content in to accumulator C109 DCR B 05 ; Decrement the B register c o n tent C10A INX H 23 ; Increment the HL register pair C10B ADD M 86 ; Add the memory content to accumulator C10C JNC C110 D2 ; Jump if carry = 0, to C110 H C10D 10 ; C10E C1 ; C10F INR C 0C ; Increment the C register content C110 DCR B 05 ; Decrement the B register content C111 JNZ C10A C2 ; Jump if no zero to C10A H C112 0A ; C113 C1 ; C114 STA C300 32 ; Store the accumulator content (sum) at C300 H C115 00 ; C116 C3 ; C117 MOV A C 79 ; Move the C register content to accumulator C118 STA C301 32 ; Store the accumulator content ( carry ) at C300 H C119 01 ; C11A C3 ; C11B HL T 76 ; Halt the exection
How does the assembly language can be executed by CPU?
Assembly language programs are the Low level programs. We write Assembly Language program in basically 8085 and 8086 microprocessors.We can have several registers to do opreations with. Accumulator is one most important Register in a assembly program.We use several instructions like..Arithmetic:INR - Increment AccumulatorADD B - Add Content of Reg. B with AccumulatorSUB, etc.Logical:AND - Bitwise ANDJump Instriction:JZ label - Jump to label if ZERO flaggedJC Label - Jump on CarryEtc..Example:MVI B, 06 //Load Register B with the Hex value 06MOV A, B //Move the value in B to the Accumulator or register AMVI C, 07 //Load the Register C with the second number 07ADD C //Add the content of the Accumulator to the Register CSTA 8200 //Store the output at a memory location e.g. 8200HLT //Stop the program execution
Do you have to register your car if you move stats?
Yes.
Do you need to register to vote when you move?
Yes, you need to re-register every time you move. Go to headcount.org or rockthevote.com to register, it will walk you through the process in about five minutes (literally!) for any state.
When do you have to re-register to vote?
If you move to a new city or town!
What are largest and smallest Rf values?
The largest Rf value is 1, which occurs when the compound remains at the origin of the chromatogram and does not move at all. The smallest Rf value is 0, which happens when the compound moves with the solvent front and does not adhere to the stationary phase.
What do mean by operands in microprocessor?
An opcode is a single instruction in assembly language. An operand is the data it does something with.For example, in "MOV r0, #0C", MOV is the opcode ("move this value into this register"), while r0 (register 0) and #0C (the number 12) are operands.
If we are moving from a large value to a small value where do we move the decimal?
Move it to the left.
What is it like every time you move left on a place value chart?
You reduce the value by the absolute value of the distance that you move.
If we are moving from a large value to a small value we move the decimal point to the?
If we are moving from a large value to a small value we move the decimal point to the left.
MOV D IN Microprocessor means?
MOV D,reg means: move content of the specified register (or M=memory addressed with HL) into register D
What does mvI DO IN 8085 microprocessor?
the purpose of mvi is to 8 bit data immidiatly to the register or memory example mvi b,05h will move 05h to register b
If we were moving from a large value to a small value to a small valuewe move the decimal point to the?
Move it to the left.
Why zero flag is not set in INX instruction of microprocessor 8085?
Because that is the way Intel designed the INX instruction of the 8085. The 8080 is also the same. INX increments (and DCX decrements) the 16 bit register pairs or BC, DE or HL, depending on what register pair you specify in the INX (or DCX) instruction. To check is the value is 0 after an INX (or DCX) instruction, you need to OR the values of the register pair into the A register. For example..... INX H ;increment HL register pair MOV A,H ; move H register into the accumulator ORA L ; Logical OR it with the L register JZ ADDR ; If 0 then jump to ADDR
