- Step size 34 mV
VHys Hysteresis (VBOD+ - VBOD-) BOD33.LEVEL = 0x0 to 0x3F 30 - 180 mV
Tstart Startup time(1) time from enable to RDY - 3.2 - us
Note:
  1. These values are based on simulation. They are not covered by production test limits or characterization.
  2. With BOD33.VREF_SEL = 0 and no hysteresis configured, BOD levels can be given as:

    VBOD+ = VBOD- = 1.43 + BOD Setting * Step_size
