Timing Analysis of S32K396

[Bhuvan]

I am working with NXP S32K396-NGA-DC1 Evaluation board. I wanted to configure a Flex IO pin to act as output to analyze the time it takes. I need guidance on how we use a particular port, set it and clear it. And also, how can we link the variable to the flex io pin on the board. I want to configure any pin for connecting it to Logic Analyzer and observe it externally.

Thanks,

Bhuvan.

Hi,

using SIUL2 MSCR register you can configure function for respective MCU pad. Refer to chapter 4.4 Signal Multiplexing sheet of the device RM to explain that.
Once FLEXIO functionality is selected on desired MCU pin, the FlexIO module can drive the pin based on FlexIO configuration. Usually the FlexIO is used to emulate communication protocols etc using its timers/shifters, but also FlexIO can override this and drive its channels directly to perform GPIO based functionality. See chapter 75.3.3 Pin operation for more info.
