TPS65987D: About cmdx datax register

Part Number: TPS65987D

I’d like to use EC to send command to TOS65987. However in the “Host interface technical reference manual „ there is no detailed description about the cmdx register. I want to know how to send the 4cc command to the device? Thanks!

Thanks for your information.I have read the article you provide and it mentioned the cmdx register address is 0x08 or 0x10, the datax register address is 0x09 or 0x11. However I can’t find any detailed information about these two registers. The article provides a piece of code which includes the function “ExecCmd” but no description of this function is provided neither. Would you please offer more detailed information about the two registers and how to execute 4cc command from EC? Thanks!
