Can we use DAI pins of 21489 as GPIO. If yes please let me know how to program the SRU for this.
Thanks & Regards,
Yes it is possible to use DAI pin as GPIO pins.
You would like to go through the following forum thread which discusses the similar issue:
Please let me know if this helps or not.
Thank you for the reply. I went through that discussion, but i couldn't get some of its points.
Can you please give me the SRU code to use DAI_P01 as input and DAI_P02 as output. Also let me know how to access these GPIO's in rest of the code.
In order to use DAI_P01 as input and DAI_P02 as output, following SRU initialization can be used:
In the above code, the DAI_PB02 pin output is routed to DAI_PB01 input pin.
Apart from this, I would suggest you to kindly refer to the Application Note EE-243, which explains how to use the Expert DAI plugin to configure the Signal Routing Unit. The link for the application note is given below:
Please let me know in case you have any further queries/doubts.
