By default, the wrist configuration is available for use. If the platform is a wrist operated device, then
there is no need to overwrite the step counter parameter values. If the configuration needs to be
modified then the following steps must be followed:
1. Disable step counter, step detector, and activity detection
2. Modify the 25 parameters of step counter
3. Enable step counter, step detector, and activity detection
After re-enabling the features, the new parameters value will be used.
Customized Step Counter Sensitivity Configuration (overwrites Step Counter Presets)
The Step Counter and Detector sensitivity can be modified manually by setting the step counter
parameters in the register map with the support of the corresponding field application engineer. The
default parameters are set by the step counter preset (phone/wrist) which is used.
