DE10 Nano J8 2x5 pins

Hello,

What are the pins for the J8 2x5 header on the DE10-NANO? The manual says

"In addition, the DE10-Nano has one external JTAG Header (J8) reserved for users toconnect to JTAG chain of the DE10-Nano via external blaster. The J8 header is not installed,

so users need to solder a 2.54mm 2x7 male pin header if it is necessary."

J8 is actually 2x5. Nowhere is there a description of the 10 pins. Does anyone know what the pins are?

Thanks
