8.2.2.5 Calculating Minimum Sensor Frequency
Use Equation 19 to calculate the minimum sensor frequency.
Equation 19. 
where
- N is 227.51
For this example, round the value of N up to 228. This value must be written into the watchdog timer register, which is used to wake up the internal circuit when the sensor is saturated.
