Note:
1. VBOD = VBOD- = 1.5 + LEVEL[7:0) * Level_Step LEVEL[7:0] is calibration setting bus of threshold
level.
2. VBOD+ = VBOD- + N * HYST_STEP N = 0 to 15 according to HYST[3:0] value HYST_STEP =
Level_Step.
3. Hysteresis OFF mode, HYST[3:0] = 0x0.
4. Hysteresis ON mode, HYST[3:0] = 0x1 to 0xf; Min/Typ/Max values given for 0x2.
5. At the upper side of LEVEL[7:0] values depending on the Hysteresis value chosen with HYST[3:0],
the VBOD+ level reaches an overflow, e.g., for HYST[3:0] = 0d2 the hysteresis is 2 x Level_Step =
12 mV up to position 253 and position 254 to 255 above must not be used.
