1 X: supported.
2 When the CAN peripheral is used, only the first 768 bytes are available to the USB. The last 256 bytes are used by the CAN.
3 The USB and CAN share a dedicated 512 bytes SRAM. They can then be used in the same application but not at the same time.
4 The dedicated SRAM is used exclusively by the USB endpoints (not shared with any other peripheral).
5 Internal FS OTG PHY support.
6 X: supported.
7 Bi-directional (including EP0)
8 The dedicated SRAM is used exclusively by the USB endpoints (not shared with any other peripheral).
9 Internal FS OTG PHY support.
10 Internal HS OTG PHY support.
11 X: supported.
12 Except for STM32L47x/L48x devices.
13 Bi-directional (including EP0)
14 The dedicated SRAM is used exclusively by the USB endpoints (not shared with any other peripheral).
15 Internal FS OTG PHY support.
