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 (EMC1701-1 only) 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 5.27.
