Note:
1. Due to internal dropout, the DC-DC output will never be able to reach its input voltage, V_VREGVDD
2. LP mode controller is a hysteretic controller that maintains the output voltage within the specified limits
3. In EMU_DCDCMISCCTRL register
4. Drive levels are defined by configuration of the PFETCNT and NFETCNT registers. Light Drive: PFETCNT=NFETCNT=3; Medi-
um Drive: PFETCNT=NFETCNT=7; Heavy Drive: PFETCNT=NFETCNT=15.
