Instructions for Use

1. Power Supply:

   • Ensure the supply voltage is within the specified range (2.0V to 5.5V).
   • Connect Vdd to the positive power supply and Vss to ground.

2. Clock Configuration:

   • Connect an external clock source or crystal oscillator to the OSC1 and OSC2 pins.
   • For a 20 MHz operation, use a 20 MHz crystal or resonator.

3. Programming:

   • Use an ICSP programmer to program the device.
   • Connect the MCLR pin to a high voltage (13V) for programming mode.
   • Follow the programming algorithm provided by Microchip for the PIC16C55.

4. I/O Configuration:

   • Configure I/O pins as inputs or outputs using the TRIS register.
   • Set the direction of each pin in the TRIS register (1 for input, 0 for output).

5. Timer Setup:

   • Initialize the timer by setting the appropriate bits in the T0CON register.
   • Enable the timer interrupt if needed by setting the corresponding bit in the INTCON register.

6. Interrupt Handling:

   • Enable global interrupts by setting the GIE bit in the INTCON register.
   • Write interrupt service routines (ISRs) to handle specific interrupt sources.

7. Watchdog Timer:

   • Enable the WDT by setting the WDTE bit in the configuration word.
   • Clear the WDT periodically in your main loop to prevent reset.

8. Brown-out Reset:

   • Enable BOR by setting the BOREN bit in the configuration word.
   • The microcontroller will reset if the supply voltage drops below the brown-out threshold.

9. Low-Power Modes:

   • Enter sleep mode by executing the SLEEP instruction.
   • Wake up from sleep mode using an interrupt or external reset.

10. Reset:

    • A reset can be generated by pulling the MCLR pin low or by a watchdog timer timeout.
    • After a reset, the program counter is set to 0x0000.
