General-purpose buttons (B1 and B2)
There are two general-purpose buttons (B1 and B2) available on the top side of the board.
Button B1 can be disconnected from the input CPU board by soldering out resistor R56 and
button B2 by soldering out resistor R61.
5.10 LEDs
There are 4 general-purpose LEDs (LD1-LD4) available on the top side of the board. All
LEDs are driven on when the related GPIO pin is driven high.

Description
Configuration
JP7
Connects the +2.5 V ADC evaluation board ADC supply
voltage to the ADC_VREFP pin of the CPU board (Default).
Connects the external ADC application supply voltage to the
ADC_VREFP pin of the CPU board.
JP8
Connects the evaluation board GND of the ADC supply voltage
domain to the ADC_VREFN pin of the CPU board (Default).
Connects the external ADC application GND (lower limit)
supply voltage to the ADC_VREFN pin of the CPU board.
