About 440p_ComExpress CN1B B055

Jump to: navigation, search

I am investigating the connection relationship between Kingfisher (* 1) and StarterKit (* 2). (* 1), B055 of 440p_ComExpress is named IrqEXT0xE8 and it is connected with INT of U11 (TCA9539QPWRQ1).
(* 2), B055 of 440p_ComExpress is named AVB_AVTP_MATCH / SCL5 and is connected to B11 (AVB_AVTP_MATCH_A) of R-Car SiP.
How will it work (how do you communicate) with B055 when connecting (* 1) and (* 2) together?

440p_ComExpress B055 is an output terminal (INT output of IO Expander) for Kingfisher.
Even for StarterKit I think that it is an output terminal (AVB_AVTP_MATCH output of R - CarGen 3).
Therefore, I think that the outputs collide with each other.
Is my understanding wrong?

B055 of KF will be used as GP2_13(input) instead of AVB_AVTP_MATCH.
