Which uc will you use?
You could send the value using uart and a terminal program, then use the value in the uc to generate a squarewave with that frequency with the help of a timer.
I don't remember all of the context of this book, but it might be something similar to what you are looking for:

Ok, does this link work for you? https://www.melexis.com/Assets/MLX90614-SMBus-implementation-in-PIC-MCU-5229.aspx
If not go to Melexis webpage and search for MLX90614, then click "applications". After that look for "MLX90614 SMBus implementation in PIC MCU" on the list of documents.
I think...
You do not need to calculate the PEC when you are reading from the sensor, unless you are using it in a noisy area where you could get corrupt data.
As I said in the other thread you started, this should help: https://www.melexis.com/Assets/MLX906...-MCU-5229.aspx. Explains for both assembly...
The experience I have is not with mlx90614 but with mlx90615. But I think they should be quite similar.
Are you talking about coding for PEC calculation? For what reason do you need to know the PEC?
When I changed the adress of the MLX90615 that I am using I manually calculated the PEC by this...
