Notes:
1.
This pin is not grounded on the Bengal since it can be used to detect the presence of an mSATA
module versus a PCIe Mini Card. Grounding this pin is available as an option on custom boards.
2.
This pin is not grounded on the Bengal to make it available for mSATA module detection.
3.
This signal drives the blue LED activity indicator at location D12 in the lower right corner of the
board (refer to
module.
4.
Some PCIe modules use this signal as a second Mini Card wireless disable input. On the
Bengal, this signal is available for use for mSATA versus PCIe Mini Card detection. There is an
option in the BIOS Setup utility for setting the mSATA detection method.
