Hello,
Following my previous post, it is now clear to me that a pin/ball input buffer is connected to all multiplexed functions on that pin/ball. This is clearly stated on page 222 of SPNU503B. My question is related to pull control. As an example, ball V10 is multiplexed to 4 functions: MIBSPI3NCS[0], AD2EVT, GIOB[2] and N2HET2_PIN_nDIS. Each of them (at least the first 3 for sure) have control on pull direction, pull disable and open drain. Am-I right to state that the pull direction, pull disable and open drain are also multiplexed, so only the one selected by the IOMM will have control on the input? I have prepared the attached drawing, based on Figure 4-2 of SPNU503B, and added 3 multiplexer of what I think is the topology.
Thanks,
Hugues
