1.2 Power Supply LEDs
LEDs are installed in several places on the EVM to provide the user indication that power-
supplies are connected correctly. The VDD and VP_OTP connections on the PGA400-Q1 have
LEDs to indicate that power is applied. Also, there are two LEDS that indicate that the USB
power supplies on the TI-GER boards are present.
