SUPC.BOD33.LEVEL[7:0] = 0x00 (Min Value) ,

SUPC.BOD33.HYST[3:0] = 0x02

1.60—1.72

SUPC.BOD33.LEVEL[7:0] = 0x19 (Recommended Value) ,

SUPC.BOD33.HYST[3:0] = 0x02

1.62—1.74

SUPC.BOD33.LEVEL[7:0] = 0x1C (Recommended Value) ,

SUPC.BOD33.HYST[3:0] = 0x02

2.93—3.32

SUPC.BOD33.LEVEL[7:0] = 0xFF (Max Value) ,

SUPC.BOD33.HYST[3:0] = 0x00

Note:
  1. VBOD(min) = (1.5 + (SUPC.BOD33.LEVEL[7:0] * VBOD33LEVEL_STEP))

    VBOD(max) = (VBOD(min) + (SUPC.BOD33.HYST[3:0] * VBOD33HYST_STEP))

  2. If a hysteresis value is programmed, the following equation must be respected to avoid any overflow on VBOD(max) : LEVEL[7:0] value < 255 - HYST[3:0] value.
