Instructions for Use

1. Power Supply:

   • Connect the VCC pin to a stable 5V power supply.
   • Ensure GND is properly connected to ground.

2. Clock Input:

   • Provide an external clock signal to the CLK input pins of each counter channel.
   • The frequency should not exceed 30 MHz.

3. Programming Counters:

   • Use the control word register to program the operation mode of each counter.
   • Load the desired count value into the respective counter registers via data lines.

4. Control Logic:

   • Set up the control logic to handle read/write operations and mode settings.
   • Refer to the specific datasheet for the control word format.

5. Output Configuration:

   • Configure the output pins based on the application requirements (e.g., square wave, one-shot).
   • Monitor the OUT pins for the generated timing signals.

6. Reset Functionality:

   • Implement reset functionality if required by setting appropriate bits in the control register.

7. Testing:

   • After setup, test the device with known inputs to verify correct operation.
   • Adjust programming as necessary to meet timing specifications.

For detailed information on control words and specific operational modes, refer to the official datasheet provided by the manufacturer.
