Field
31–11 Reserved, always cleared.
10–9 Serial mode. Indicates presence of serial interface. Always 11.
SM 11 Serial engine is present and defaulted for all FS/LS operations
8–6 PHY Mode. Indicates USB transceiver interface used. Always reads 111.
PHYM 111 Software controlled reset to serial FS
5–4 PHY width. Indicates data interface to UTMI transceiver. This field is relevant only for UTMI mode; therefore, it is
PHYW relevant only to the USB OTG module in UTMI mode. Always reads 00.
00 8-bit data bus (60 MHz)
3 Reserved, always cleared.
2–1 Reserved. For the USB OTG module, always 10; for the USB host module, always 01.
