Registers in 8051 Microcontroller

Obviously, registers are the keen role in microcontroller process. Why we use these register because it provides a fast way to collect and store a data.

Why registers?

    Using microcontroller needs to perform one action whatever it may be that is called as microcontroller process. For instance, I have given one operation to the controller that can't do in the memory. it's a needs a register to manipulate the data, perform the task, process and store. that is register.


A register to say simply, it has a small place in CPU, that can store a small amount of data to perform various operations such as a multiplication, subtraction, addition and division etc.

For instance, we have already a memory why we use these are used for store what it stores.? because it stores the address of the memory location. for every data, we have some memory location that is going to store in the register.

In 8051 family microcontroller RAM have 256 bytes of memory. According to this RAM memory, two types of the register are we have, those are

1. General purpose registers.
2. Special Function Register.

               RAM ----- 256 bytes

1. General Purpose Registers --- 128 bytes.

2. Special Function Registers ---- 128 bytes.


                                8051 RAM Memory




 In a general purpose register normally has a 4 bank 4 banks of registers,

And in the next podcast, you will let to know pragmatic and rigorous about these types of registers.

General puprose registers in 8051.

Well, in yesterday's podcast discussed on registers in 8051, two types of a register, general purpose registers are today's article all about. The general purpose registers are called as RAM memory in 8051. It has 128 bytes of memory for this general purpose registers. These general purpose registers are divided into 3 areas, those are  Banks. Bit addressable areas. scratchpad areas.                                     Let we discuss clearly, Banks    In this bank, 4 types of banks are there like  bank 0 bank 1 bank 2 bank 3 In each bank has 8 registers those are R0 to R7. All these general purpose registers are byte addressable registers. An image is shown in below for better understanding,                                     ...

TCON Special Function register.

If a counter is programmed to be a timer, it will count the internal clock frequency of the 8051 oscillator 12d. As an example, if the crystal frequency 6 MHz, then the timer clock will have a frequency of 500kHz.   The timers may operate in any one of four modes that are determined by the mode bits. In that the timer control TCON it is a special function register. TCON:   Pin Description of TCON: Bit Symbol TCON Bit Function 7 TF1l Timer 1 Overflow flag. Set when timer rolls from all 1's to 0. Cleared when processor vectors to execute interrupt service routine located at program address 001Bh. 6 TR1l Timer 1 run control bit. Set to 1 by a program to enable the timer to count; cleared to 0 by the program to halt timer. 5 TF0 l Timer 0 Overflow flag. Set when timer rolls from all 1's to 0. Cleared when processor vectors to execute interrupt service routine located at program address 000Bh. 4 TR0l Timer 0 run control bit. Set to 1 by a program to ...

TMOD Special Function Register.

TMOD register As we know there are 2 timer registers in 8051. Timer 0 and timer 1. Both of these registers use the same register called TMOD to set various timer operation modes. TMOD is an 8-bit register, in which lower 4 bits are for Timer 0 and upper 4 bits are for Timer 1. See table below. MSB ---- LSB GATE C/T M1 M0 GATE C/T M1 M0 TIMER 1 TIMER 0 Bit Description: Bit TMOD Bit Function 7 Gate -- OR gate enable bit which controls RUN/STOP of timer 1. Set to 1 by the program to enable the timer to run if bit TR1 in TCON is set and the signal on external interrupt is high. Cleared to 0 by the program to enable time to run if bit TR1 is set. 6 C/ T  -- Set to 1 by the program to make timer 1 act as a counter by counting pulses from external input pins 3.5. Cleared to zero by the program to make timer act as a timer by counting internal frequency. 5 M1 -- Timer/counter operating mode select bit 1. Set/cleared by the...
