Question

What's the best way to disable the DSI (mainly in terms of EMC) ?

Hard to believe, we have an F469 MCU (chosen due to a number of attributes) that will not use the DSI.

Other than with standard GPIOs, were unused pins are configured as outputs and set to 0 (zero), this doesn't seem to be possible with the DSI I/O pins. Now what ?

Best regards

What's the issue?

Can't you just disable, or not configure the interface, and just tied the pins off with pull downs?

Perhaps discuss concerns with the local FAE supporting your account? Contact local sales office.

Tieing the pins down is an option.

Just asking to make sure we didn't miss something comparable to the active "controlled low" of the GPIOs.
