Embedded Processor and Microcontrollers

Title : (i)  Embedded Processor and Microcontrollers

           (ii) To Introduce keypad of MTS-86C Microprocessor Trainer

Objectives:  To get familiar with Processor, microcontroller practically

                            Build in MTS-86c trainer.

Procedures:

A microprocessor is the central processing unit of a computer constructed

With in  a single chip. To make a complete microprocessor it needs to be

Connected to

·        Memory to store data.

·        RAM

·        ROM

·        I/O

·        Control circuit.

Serial Port:  RS232, USB port, Ps2

Types of Microprocessor:

(i)                Specific Microprocessor

(ii)             General Purpose Microprocessor

Difference b/w Microprocessor and Microcontroller:

Microprocessor consume more power as compare to Microcontroller.

Speed of Microprocessor in higher than Microcontroller.

Its size is less than Microcontroller.

Microprocessor cannot work independently.

Functions of Keypad MTS-86c:

EB = Examine Byte,   Ax= Accumulator, ER= Examine Register

Bx= Base Register, Go = command, CX= count Register

ST= Single step, DX= Data Register, IB= Input byte

SP= State pointer, OB= O/P byte, BP= Base Pointer

Mv= move, SI= sorce index, Ew= Examine word

DI= Destination index, CS= Code Segment, Ow= O/P word

Ds= Data segment, SS= State segment, Es= Extra Segment

IP= Instruction Pointer , FL= Flag Register.

->Examining and Modifying contents of memory address:

Seg: offset

è      Press 0 ( Examine byte)

è      Press 1(0000:0001)

è      Press 0(0000:0010)

è      Again Press 0(0000:0100)

è      Using (:) seg and offset become same

è      Press 5 (0100:0005)

è      Press , again to get (0100:0007)

è      , = to see saved data

è      Press dot to save data

Storing Data on Register:

Press 1  ( Examine Register)

Press 2 (Go Command)

Edit, Then Press . To save.

Then Press reset to see stored data.
