Instructions

1. Power Supply:

   • Ensure the supply voltage (VDD) is within the range of 2.7V to 5.5V.
   • Connect the power supply to the VDD and GND pins.

2. Reset:

   • To reset the counter, apply a low pulse to the RST pin for at least 1 μs.

3. Input Signal:

   • Connect the input signal to the CLK pin. The maximum input frequency is 20 MHz.

4. Counter Configuration:

   • Set the counter resolution by configuring the appropriate registers. The counter can be set to 1 to 32 bits.

5. Reading the Counter:

   • Use the read cycle time (tRW) to ensure proper timing when reading the counter value. The typical read/write cycle time is 100 ns to 200 ns.

6. Output:

   • The output load current (IOL) should not exceed 24 mA per pin.
   • Ensure the output high voltage (VOH) and output low voltage (VOL) levels are within the specified ranges.

7. Temperature Considerations:

   • Operate the device within the temperature range of -40°C to 85°C.
   • Store the device within the temperature range of -65°C to 150°C.

8. Standby Mode:

   • To enter standby mode, set the appropriate register bit. The typical supply current in standby mode is 0.1 μA to 0.2 μA.

9. Programming:

   • Refer to the device datasheet for detailed programming instructions and register configurations.
