TUSB422: DEBUG_ACC_CONNECTED bit in Power Status Register

Joel Brassfield

Part Number: TUSB422

What resistor values must be placed on the CC1 and CC2 lines in order for the TUSB422 to set its DEBUG_ACC_CONNECTED bit in the Power Status Register?

Hi Joel,

Per appendix B of the USB-C spec, CC1 and CC2 should either be PU by a value RP or PD by a value RD.

It's best to use a captive cable to connect CC1/CC2, or directly connect to the TS at the port.

Thanks,

Ryan
