Hi
I am working on a custom board based on STM32MP157A . For USBH_EHCI while checking the register (USBH_EHCI_INSNREG05) mentioned in the reference manual (RM0436) it was mentioned to refer to UTMI specification. could you please suggest / share me the vendor specific UTMI specific document for the below attached image
Thanks&Regards

Hi @Srikanth1 ,
I have asked internally details for those 'vendor specific' fields. My first assumption is that bits 0 to 12 are not used in our implementation and might need to be removed from the documentation.
regards.

Hi,
I got confirmation from expert than the bits 12-0 are not connected in our design and so will do nothing (i.e. vendor specific feature not used).
Future revision of Reference Manual will be updated to reflect this.
Regards.
