I have encountered a bit of understanding gap in which parts of a controller are common and which are dedicated to each channel.
Hi Rooper
1. for uSDHC usage one can look at SDK example
https://github.com/RT-Thread/rt-thread/tree/master/bsp/imx6sx/iMX6_Platform_SDK/sdk/drivers/usdhc
2. all uSDHC instances are independent modules. So SYS_CTRL resets only one module.
Best regards

Thank you for answer. As I understand, since each instance is seperate module, buffer, DLL and clock are seperate too? Documentation specifies broadcast commands, which are send to all cards. Are they confined to module or send to all modules?
yes they are separate.
Best regards
