AM2431: In sysconfig 1.20, what is the gpio rx parameter?

Part Number: AM2431
Other Parts Discussed in Thread: SYSCONFIG

Tool/software:

We have a example.syscfg file that we have been editing with sysconfig 1.17

We are trying to move to sysconfig 1.20 and when we open the syscfg file, it adds a .rx parameter to every gpio and sets it to true.

What is the purpose of the rx parameter and should we leave how sysconfig set it? (true)

Also noticed when we add a new GPIO, rx defaults to off.

    You are seeing the RX parameter to be true because in your example.syscfg file which was created earlier using older version of MCU+SDK, RX parameter was enabled by default.

    Please refer below screenshot.

    Please refer to the section 5.1.1.4 Pad Configuration Registers of TRM to know about the details regarding the PAD config registers.

    Please refer below image.

    With the latest MCU+SDK, there  is a major change in the device data of GPIO. The RX Parameter of GPIO is now disabled by default.

    Please refer Release notes #GPIO for more details. 

    See the below screenshot.
