Tool/software: Code Composer Studio
I connected TDA3 to SD card and configured it as SD Host.
Then I need to switch both the Host and the Card to UHS mode. There is enough information in SD Physical Layer Specification how to switch the card to UHS mode. But this is not so with the Host.
I've found needed bit fields in MMCHS_AC12 register, such as UHSMS, V1V8_SIGEN etc. in TDA3 Reference Manual. But there is no any UHS Mode Switch flow in the document. I haven't also found it in examples.
So, where can I find this information?
