3.2 Configuration Jumpers
The S5U13517P00C100 has 6 jumpers which configure various board settings. The jumper positions for each
function are shown below.
J1, J2, J3 - Power Supplies for the S1D13517
J1, J2, J3 can be used to measure the current consumption of each S1D13517 power supply.
When the jumper is at position 1-2, normal operation is selected.
When no jumper is installed, the current consumption for each power supply can be measured by connecting an
ammeter between pins 1 and 2 of the jumper.
The jumper associated with each power supply is as follows:
J1 for COREVDD
J2 for IOVDD
J3 for PLLVDD
