Automatic Gain
Control (AGC)
algorithm: Set the
target percentage of
the full-scale ADC
range that the
automatic gain
control (AGC)
algorithm uses.

Wrist Heart Rate
Monitor (WHRM)
algorithm: Set the
sample rate for the
WHRM algorithm.
The WHRM algorithm
is configured to use
the LED1 and Photo-
diode 1 (25Hz sample
rate) and is
compatible with the
MAX86141 AFE, KX-
122 accelerometer.
