Power Supply Setup:
- Ensure Vdd is within the specified range of 2.0V to 5.5V.
- Connect Vss to ground.
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.
Port Initialization:
- Configure I/O pins using TRIS registers to set direction (input/output).
- Initialize port states using PORT registers.
Timer Setup:
- Configure Timer0 using T0CON register for desired operation mode and prescaler settings.
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.
Programming:
- Use ICSP for in-circuit programming or external parallel programmer for initial code loading.
- Follow manufacturer’s guidelines for programming EEPROM/EPROM memory.
Low Power Operation:
- Enter Sleep mode using SLEEP instruction to reduce power consumption.
- Wake up from Sleep mode via interrupts or watchdog timer timeout.
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.
