Hi dear,
A scan counter is provided to allow confirmation of receipt of the Scan and Measure commands. This is a 4-bit counter located in the Scan Count register (page 1, address 6’h16). The counter increments each time a Scan or Measure command is received. This allows the host microcontroller to compare the counter value before and after the Scan or Measure command was sent to verify receipt. The counter wraps to zero when overflowed. The scan counter increments whenever the ISL94212 receives a Scan or Measure command. The ISL94212 does not perform a requested scan or measure function if there is already a scan or measure function in progress, but it still increments the scan counter.
Thanks
