4.9 VIN/VOUT Mux Selection

The multiplexed video Input/Output signals from Expansion connector connected to three 12 bit 1:3 De-muxer U10, U11 and U12 IC Mfr. Part# SN74CBT16214CDGGR. One channel (Port B1) of the de-muxer interfaced with HDMI transmitter, the second channel (Port B2) interfaced with parallel camera interface and the third channel (Port B3) interfaced with FPD display port on the infotainment expansion board. For Mux selection GPIO details, see Section A.2.
