Hi,

 

could you please confirm our thoughts about FCCU EOUT pins behaviour during and after reset. Reference manual states the following:

Lets assume we PTE15/PTE16 (or PTF14/PTF15) as EOUT pins. All four of these pins have High-Z written in these columns in S32K344_IOMUX.xksx table:

Is there any other info we are missing or we can be sure that EOUT pins will not be toggled during/after any kind of reset?

 

 

Best regards,

Matej

Hello,

They wont be toggled during reset as the FCCU module is not active therefore no toggling (protocol) can be active.

Is there any other info we are missing or we can be sure that EOUT pins will not be toggled during/after any kind of reset?

The pin is during reset in defined (high-Z) state or for functional reset driven by FCCU, but only if set:
