Bits 1 - 0 - CS_RNG[1:0] - Determines the Current Sense maximum expected voltage (full scale range)

as shown in Table 5.32.

5.21 Peak Detection Configuration Register

The Peak Detection Configuration register controls the threshold and durations used by the Peak

Detection circuitry. At all times, the Peak Detection threshold and duration are set by the values written

into this register. The resistors on the TH_SEL and DUR_SEL pins are used to determine the initial

values of this register and will not be retained if the value is over written by the user.

These values may be updated at any time via the SMBus.

Bits 7-4 - PEAK_DET_TH[3:0] - Determines the Peak Detector Threshold level as shown in Table 5.34.
