AD7124-8 bridge to UART. SPI to UART converter.

Hello,

I use AD7124-8 on my devices. Recently we discovered that we must add some new functionality to the device, and we are in a lack of free CPU pins. Thus, there is an idea, if it is possible to connect AD7124-8 to the UART port, instead of SPI.

Does anyone already test something like this? Can anyone give any insights or help with a nice link for an explanation?

Thank you!
