    executes the first instruction from a subprogram SUB_1 and reads in the next one.
    Pin description
    PIC16F84 has a total of 18 pins. It is most frequently found in a DIP18 type of case but can also be found in SMD case which is smaller from a DIP. DIP is an abbreviation for Dual In Package. SMD is an abbreviation for Surface Mount Devices suggesting that holes for pins to go through when mounting, aren't necessary in soldering this type of a component.
    Pins on PIC16F84 microcontroller have the following meaning:

    Pin no.1 RA2 Second pin on port A. Has no additional function
    Pin no.2 RA3 Third pin on port A. Has no additional function.
    Pin no.3 RA4 Fourth pin on port A. TOCK1 which functions as a timer is also found on this pin
    Pin no.4 MCLR Reset input and Vpp programming voltage of a microcontroller
    Pin no.5 Vss Ground of power supply.
    Pin no.6 RB0 Zero pin on port B. Interrupt input is an additional function.
    Pin no.7 RB1 First pin on port B. No additional function.
    Pin no.8 RB2 Second pin on port B. No additional function.
    Pin no.9 RB3 Third pin on port B. No additional function.
    Pin no.10 RB4 Fourth pin on port B. No additional function.
    Pin no.11 RB5 Fifth pin on port B. No additional function.
    Pin no.12 RB6 Sixth pin on port B. 'Clock' line in program mode.
    Pin no.13 RB7 Seventh pin on port B. 'Data' line in program mode.
    Pin no.14 Vdd Positive power supply pole.
    Pin no.15 OSC2 Pin assigned for connecting with an oscillator
    Pin no.16 OSC1 Pin assigned for connecting with an oscillator
    Pin no.17 RA2 Second pin on port A. No additional function
    Pin no.18 RA1 First pin on port A. No additional function.
