Important note:
In the 3.3V configuration, the internal regulator is bypassed. The regulator has to be disabled to
avoid extra power consumption.
• Bit 0 – REGDIS: Regulator Disable
Set this bit to disable the internal 3.3V regulator. This bit should be used only in a full 3.3V appli-
cation. This bit is reset to 0 in every case. The firmware has the responsability to set it after each
reset if required.
