The S5U13709P00C100 Evaluation Board is designed to generate HIOVDD, NIOVDD,

COREVDD and PLLVDD from 5V via the S5U13U00P00C100 USB Interface Board. 5V must be

supplied from the S5U13U00P00C100. JP1 on the S5U13U00P00C100 USB Interface Board

should be set to position 2-3. 3.3V power supply is generated by one voltage regulator (U3) and

fixed output. HIOVDD and NIOVDD can be selected 3.3V or 5V using jumper JP9 and JP10.

COREVDD is possible to select HIOVDD, NIOVDD or LDOVDD0. PLLVDD are possible to select
