If an On-Chip LDO Output is not Used
If an LDO is not used, leave the LDOO output pin floating
CVDDRTC MUST NEVER be supplied by any on-chip LDO outputs
If DSP_LDOO is not used:
RESET must be asserted until power supplies and clocks are stable (internal Power on Reset logic disabled when LDO not used)
DSP_LDO_EN should be tied high to LDOI
