Does the register DEFLDO1 exist? On page 35 of the data sheet it states "the output voltage for LDO1 is defined by the sttings in register DEFLDO1." This is the only place in the data sheet that this register is mentioned? Am I misunderstanding what this is telling me or is this a typo? I am trying to enable enable LDO1 to 3.3V, how would I acheive this?
This appears to be a typo. The datasheet should read, "the output voltage for LDO1 is defined by the sttings in register LDO_CTRL1."
To set the voltage of LDO1 use the 4 LSBs of LDO_CTRL1.
For 3.3V, set LDO_CTRL1[3:0] to b1111.
The bits are named LDO1, LDO1, LDO1, LDO1.
