⚙️ Bitwise Visualizer & Logic Tester

🎯 Getting Started

This tool simulates microcontroller registers and bitwise operations:

• Click bits in Register A or B to toggle them (0 → 1 or 1 → 0)
• Choose operation from the operator buttons (AND, OR, XOR, etc.)
• See results instantly in Register C with hex/decimal values
• Switch bit width between 8-bit and 16-bit modes

⚡ Bitwise Operations

• AND (&): Result bit is 1 only if both input bits are 1
• OR (|): Result bit is 1 if either input bit is 1
• XOR (^): Result bit is 1 if input bits are different
• NOT (~): Inverts all bits in Register A (ignores B)
• Left Shift (<<): Shifts bits left, fills with 0s on right
• Right Shift (>>): Shifts bits right, fills with 0s on left

🔧 Microcontroller Use Cases

• Set a bit: Use OR with a mask (e.g., PORTB | 0x04 sets bit 2)
• Clear a bit: Use AND with inverted mask (e.g., PORTB & ~0x04 clears bit 2)
• Toggle a bit: Use XOR with a mask (e.g., PORTB ^ 0x04 toggles bit 2)
• Check a bit: Use AND to isolate (e.g., if (PORTB & 0x04) checks bit 2)

📝 Quick Tips

• Hex values are prefixed with 0x (standard C notation)
• In JavaScript bitwise ops, use & 0xFF for 8-bit mask or & 0xFFFF for 16-bit
• Shift operations respect the current bit width (overflow bits are discarded)
• Use the preset buttons to quickly load common bit patterns
