Instructions for Use

1. Power Supply:

   • Connect Vdd to the positive supply voltage (2.0V to 5.5V).
   • Connect Vss to ground.

2. Oscillator Configuration:

   • Configure the oscillator using the OSCCON register.
   • External clock or crystal can be connected to the OSC1 and OSC2 pins.

3. Program Memory:

   • Program the device using an ICSP programmer.
   • Ensure the correct configuration bits are set for the desired operation.

4. Data Memory:

   • Access RAM and EEPROM using standard read/write operations.
   • Use the EECON1 and EECON2 registers for EEPROM operations.

5. Analog-to-Digital Converter (ADC):

   • Configure the ADCON0 and ADCON1 registers to select the input channel and conversion mode.
   • Start a conversion by setting the GO/DONE bit in ADCON0.

6. Comparator:

   • Configure the CMCON register to select the comparator inputs and outputs.
   • Use the comparator outputs for various applications like level detection.

7. Timer/Counter:

   • Configure T0CON and T1CON registers to set up the timers.
   • Use the TMR0 and TMR1 registers to read or write timer values.

8. Capture/Compare/PWM (CCP1):

   • Configure CCP1CON to select the mode (Capture, Compare, or PWM).
   • Use the CCPR1H and CCPR1L registers for PWM duty cycle settings.

9. Interrupts:

   • Enable interrupts by setting the GIE bit in the INTCON register.
   • Configure individual interrupt sources using the corresponding control registers.

10. Power Management:

    • Use the SLEEP instruction to enter low-power mode.
    • Wake up from sleep using interrupts or external reset.

11. Reset:

    • Power-on reset (POR) and brown-out reset (BOR) are automatically enabled.
    • Use the MCLR pin for manual reset.

12. Programming:

    • Use an ICSP programmer to program the device in-circuit.
    • Ensure the correct configuration bits are set for the desired operation.
