HD3SS3220: HD3SS3220RNHR_Pin27 function check for Arcadyan

Part Number: HD3SS3220

hi Team,

Please help us check the function of pin27, it will be low when CC is on DFP or DRP acting as DFP. Could we use this to enable or disable next stage without any SW control when the USB-C port attached a USB flash drive (DFP)?

1: Make sure FP6861 is low enable.

2: vbus detect should connect to VbusB, not 5v_usb.
