[1]
HPD_B_FLT is an internally derived signal, not an input to CBTL12131. HPD_B_FLT will follow input HPD_B.
[2]
System controller will assert AUX_TERM_SNK HIGH when user action prompts a ‘toggle’, hence system should configure itself as a sink.
[3]
System controller will assert AUX_TERM_SRC HIGH when it has determined that a Sink is connected, hence system should configure itself as a source.
[4]
System controller should guarantee that (AUX_TERM_SNK & AUX_TERM_SRC) is never TRUE for normal operation unless the external termination resistors are used.
[5]
AUX_TERM_SRC and AUX_TERM_SNK = TRUE are used as a disable mechanism for the integrated AUX bias network when external termination resistors are used.

Legend: high-Z = isolating, high-impedance; ACT = active, nominal-impedance.
