Instructions for Use:

1. Power Supply:

   • Ensure the supply voltage (Vdd) is within the specified range of 1.8V to 5.5V.
   • Connect the Vss pin to ground.

2. Oscillator Configuration:

   • For internal oscillator, configure the OSCCON register.
   • For external oscillator, connect the appropriate crystal or resonator to the OSC1 and OSC2 pins.

3. I/O Configuration:

   • Configure the TRIS register to set the direction of I/O pins (input or output).
   • Use the PORT register to read or write to I/O pins.

4. ADC Configuration:

   • Enable the ADC module by setting the appropriate bits in the ADCON0 register.
   • Select the desired channel using the ADCON1 register.
   • Start the conversion by setting the GO/DONE bit in the ADCON0 register.

5. DAC Configuration:

   • Enable the DAC module by setting the appropriate bits in the DACCON0 register.
   • Set the DAC output value using the DACVAL register.

6. Comparator Configuration:

   • Enable the comparators by setting the appropriate bits in the CM1CON0 and CM2CON0 registers.
   • Configure the inputs and outputs of the comparators using the CM1CON1 and CM2CON1 registers.

7. Timer Configuration:

   • Enable the timers by setting the appropriate bits in the T0CON, T1CON, and T2CON registers.
   • Set the prescaler and postscaler values as needed.

8. CCP Module Configuration:

   • Enable the CCP modules by setting the appropriate bits in the CCP1CON and CCP2CON registers.
   • Configure the mode (capture, compare, PWM) using the same registers.

9. USART Configuration:

   • Enable the USART module by setting the appropriate bits in the TXSTA and RCSTA registers.
   • Set the baud rate using the SPBRG register.

10. MSSP Module Configuration:

    • Enable the MSSP module by setting the appropriate bits in the SSPCON1 register.
    • Configure the mode (I2C or SPI) using the same register.

11. Brown-out Reset (BOR):

    • Enable BOR by setting the appropriate bits in the BORCON register.

12. Watchdog Timer (WDT):

    • Enable WDT by setting the appropriate bits in the WDTCON register.
    • Clear the WDT periodically to prevent reset.

13. Low-Voltage Programming (LVP):

    • Enable LVP by setting the appropriate bits in the configuration words.

14. Power-on Reset (POR):

    • POR is automatically enabled and will reset the device when power is applied.

15. Power-saving Modes:

    • Enter sleep mode by setting the SLEEP bit in the SLEEP register.
    • Enter idle mode by setting the IDLE bit in the SLEEP register.
