Instructions for Using MOS6502A

1. Power Supply:

   • Connect the Vcc pin to a stable 5V power supply.
   • Connect the GND pin to ground.

2. Clock Signal:

   • Apply a clock signal to the φ0 and φ1 pins. The frequency should be within the specified range (1 MHz to 2 MHz).

3. Reset:

   • To reset the processor, apply a high signal to the RST pin for at least two clock cycles.

4. Interrupt Handling:

   • For non-maskable interrupts (NMI), apply a high-to-low transition to the NMI pin.
   • For maskable interrupts (IRQ), apply a high-to-low transition to the IRQ pin. The interrupt can be masked by setting the I bit in the status register.

5. Memory Interface:

   • Connect the address lines (A0-A15) to the memory address bus.
   • Connect the data lines (D0-D7) to the memory data bus.
   • Use the read/write control signals (RD, WR) to manage memory access.

6. Programming:

   • Write your program in assembly language using the 6502 instruction set.
   • Load the program into memory and set the program counter (PC) to the start address.

7. Debugging:

   • Use a debugger or in-circuit emulator to step through your code and monitor registers and memory.

8. Power Down:

   • When not in use, disconnect the power supply to prevent damage and reduce power consumption.

9. Storage:

   • Store the MOS6502A in a static-protective bag to prevent damage from electrostatic discharge.

10. Handling:

    • Handle the chip with care to avoid bending the pins or damaging the package. Use proper anti-static precautions when handling the chip.
