Registers and fields were generated based on a set of USB-DWC configuration options.
ESP32-P4 contains 2 instances of USB-DWC with different configurations, the structure below corresponds to the HS instance.
The FS instance contains a subset of registers from HS instance, the user (HAL) is responsible for accessing only existing fields.
ESP32-P4 contains 2 instances of USB-DWC with different configurations and versions, the structure below corresponds to the High Speed v4.30a instance.
The Full Speed instance contains a subset of registers from High Speed instance, the user (HAL) is responsible for accessing only existing fields.
See ESP32-P4 "usb_dwc_cfg.h" for more details.
List of changes v4.00a -> v4.30a
- GRSTCTL register now contains the CSftRstDone bit which indicates the completion of a soft reset.
