Question Asus H370-I not documented connector

[adrhc]

Hi, what is that 6-1 pin connector (2nd image, left bottom) right above the AAFP one?

PRobably the BIOS SPI connector, to program the BIOS. (Serial Programming Interface)

Edit: No, that appears directly under the BIOS chip. Maybe an SPDIF interface?
