VADJ Voltage Control

The V rail is set to 2.5V. When the ZC706 evaluation board is powered on, the state of the
ADJ
FMC_VADJ_ON_B signal wired to header J18 is sampled by the TI UCD90120A controller
U48. If a jumper is installed on J18 signal FMC_VADJ_ON_B is held Low, and the TI controller
U48 energizes the V
