Hi All,

I am working on MPC5606s microcontroller,

My query is PSMI register is used for input pad selection only or it can be used for output pad selection ?

Kindly share your inputs to configure the PSMI register,when i want to use PSMI register for PORT pin configurations.

No, output are configured by SIU_PCR registers. Pay attention to picture below:

Thanks a lot David.

so my understanding is when PCR is configured as GPIO - input ,we need to select the pad correctly in PSMI register right?

PSMI register configures routing between pin and input of particular module.

If you only need general purpose input functionality i.e. you will read its state software way over SIU_GPDIx or SIU_PGPDIx registers, you don't need to configure PSMI registers.
