Mini PCIe (shared with mini SATA)
The conga-PA3 offers a mini PCIe slot on connector X9. This connector supports both mPCIe and mSATA devices. The PCIe and SATA signals
are routed from the SoC to connector X9 (mPCIe/mSATA slot) via a multiplexer. The multiplexer switches the incoming signals based on the
type of card inserted.
When an mPCIe or mSATA device is attached to the mPCIe/mSATA slot (connector X9), the multiplexer detects the connected device via the
signal detect pin (pin 43) and sends the corresponding signals to connector X9.
