TD.4.7.3. Try SNK DRP Connect Try.SRC DRP fails. The compliance tester mimics being a Try.SRC USB-C port. The failure is due to TCPM exiting SNK_TRY_WAIT_DEBOUNCE_CHECK_VBUS when VBUS is not present eventhough when SNK.Rp is seen. Exit to SRC_TRYWAIT from SNK_TRY_WAIT_DEBOUNCE_CHECK_VBUS only when SNK.Rp is not seen for PD_T_TRY_CC_DEBOUNCE. >From the spec: The port shall then transition to Attached.SNK when the SNK.Rp state is detected on exactly one of the CC1 or CC2 pins for at least tTryCCDebounce and VBUS is detected. Alternatively, the port shall transition to TryWait.SRC if SNK.Rp state is not detected for tTryCCDebounce.
