Instructions for Use:

1. Power Supply:

   • Connect the Vcc pin to +5V DC supply and GND pin to ground.

2. Data Bus Connection:

   • Connect the D0-D7 pins to the data bus of the microprocessor system.

3. Address Lines:

   • Connect the A0-A1 address lines to select one of the four registers (Port A, Port B, Port C, or Control register).

4. Control Signals:

   • Connect the RD (Read), WR (Write), and CS (Chip Select) signals to corresponding control lines of the microprocessor.

5. Programming:

   • Initialize the PPI by writing mode commands to the control register.
   • Configure each port as input or output based on the application requirements.

6. Ports Operation:

   • Port A and Port B can be used in any mode.
   • Port C can function as two 4-bit ports or a single 8-bit port depending on the configuration.
   • Utilize Port C for control signals such as interrupt acknowledge, handshaking, etc.

7. Interrupt Handling:

   • Configure interrupts if using strobe I/O modes to handle data transfer efficiently.

8. Bit Manipulation:

   • Use the bit set/reset capability of Port C for controlling individual bits without affecting others.

9. Application Examples:

   • Ideal for interfacing with keyboards, displays, printers, and other peripherals requiring parallel data transfer.
