Instructions for Use:

1. Power Supply Setup:

   • Ensure Vdd is within the specified range of 2.0V to 5.5V.
   • Connect Vss to ground.

2. Oscillator Configuration:

   • Choose an appropriate oscillator type based on application requirements (LP, XT, HS, EC, or INTRC).
   • Connect external components as necessary for the chosen oscillator type.

3. Port Initialization:

   • Configure I/O pins using TRIS registers to set direction (input/output).
   • Initialize port states using PORT registers.

4. Timer Setup:

   • Configure Timer0 using T0CON register for desired operation mode and prescaler settings.

5. Interrupt Handling:

   • Enable interrupts globally using GIE bit in INTCON register.
   • Set up individual interrupt sources by configuring corresponding bits in INTCON and PIE registers.

6. Programming:

   • Use ICSP for in-circuit programming or external parallel programmer for initial code loading.
   • Follow manufacturer’s guidelines for programming EEPROM/EPROM memory.

7. Low Power Operation:

   • Enter Sleep mode using SLEEP instruction to reduce power consumption.
   • Wake up from Sleep mode via interrupts or watchdog timer timeout.

8. Data Retention:

   • Data EEPROM retains data even when power is off, useful for non-volatile storage needs.

Ensure all connections are secure and follow proper PCB layout guidelines for optimal performance.
