Pinout
1. Port 0 (P0.0 to P0.7): 8-bit open-drain bi-directional I/O port, also serves as a multiplexed address and data bus for external memory.
2. Port 1 (P1.0 to P1.7): 8-bit bi-directional I/O port with internal pull-ups.
3. Port 2 (P2.0 to P2.7): 8-bit bi-directional I/O port with internal pull-ups, also serves as the high-order address byte during external memory access.
4. Port 3 (P3.0 to P3.7): 8-bit bi-directional I/O port with additional functions like serial communication, interrupts, and timer inputs.
5. RST (Reset): Resets the microcontroller.
6. ALE (Address Latch Enable): Used in external memory interfacing.
7. PSEN (Program Store Enable): Used for external program memory.
8. EA (External Access): Determines whether code is fetched from internal or external program memory.
9. XTAL1 and XTAL2: Connect to external oscillator or crystal for clock input.
These pins facilitate various functions, including general-purpose I/O, interfacing, and control operations.
