using DIGON/BL_ON for external power switches.
• Signals 1‑10 correspond to signals 1‑10 found on the X2 connector.
• X66, X67 and X69 represent jumpers X66, X67 and X69 found on the conga-CEVAL.
• The conga‑CEVAL carrier board is equipped with a Maxim MAX5362 device referred to in the diagram below as "DAC". The DAC is a 6‑bit
