Pin-out for Flexbus

This is no doubt a beginner's question. I am considering using a K61 System on Module board for a project. I need the SoM to expose FlexBus, preferably 16 bits of address and 8 bits of data (non-multiplexed). Is the Flexbus presented on fixed pins of the K61 chip? If so, which ones? Or can I allocate Flexbus to any GPIO or other pins of the chip? If so, how, and what are the restrictions (if any)? Only if the SoM exposes the necessary address and data and read/write pins will it do the job I need...

Thanks for your help.

Hello Rowan,


Take a look at the table of Chapter 10.3.1 - Pin multiplexing and Pin Assignments of the reference manual of K61.

You will see that each pin has several muxing options. You can take out the FlexBus signals by different pins.

Regards,


Santiago
