Original question:

AM3352: DEVCTL and FADDR registers

AM3352: FADDR register information

Part Number: AM3352

Hi experts,

My customer is using AM3352 and is trying to develop a driver for USB. The driver is based on the SDK sample.

Is it still required NDA to obtain register information that is not described in the TRM (SPRUH73Q), such as the FADDR register, as shown below?
Reference E2E:e2e.ti.com/.../am3352-devctl-and-faddr-registers

We checked the USB description in the TRM, but it does not explain some registers. For example, in the explanation of "16.2.8.1 USB Controller Peripheral Mode Operation", it says "Clears FADDR register to 0". However, there is no description of the FADDR register. It would be helpful if you could share a document that describes the register contents in more detail than the TRM (including information on the missing USB-related register descriptions).

Best regards,
O.H
