AM623: Superspeed USB typo/contradiction

Part Number: AM623


Believe we have a Superspeed USB typo/contradiction between p. 21 and p. 9108 of the TRM https://www.ti.com/lit/pdf/spruiv7  ?

On p, 21

1.4.13 Universal Serial Bus (USB) Subsystem
Instantiated in MAIN domain: Two instances of the Universal Serial Bus (USB) subsystem with integrated
USB2.0 PHY modulehas the following main features:
• Dual-Role Device (DRD) capability
• Support of Peripheral (aka Device) mode at Super Speed (SS at 5 Gbps), High Speed (HS at 480 Mbps), and
Full Speed (FS at 12 Mbps)
• Support of Host mode at Super Speed (SS at 5 Gbps), High Speed (HS at 480 Mbps), Full Speed (FS at 12
Mbps), and Low Speed (LS at 1.5 Mbps

On p. 9108 , I see the opposite clarification for AM62:

>> SuperSpeed (5.0 Gb/s) operation is not supported in either operational mode.

 Please advise?

    Hello Joe G.

    Thank you for the query.

    Please refer datasheet for the USBSS capabilities and thank you for pointing the discrepancy.

    I will file an internal request to have this updated.

    8.5.21 Universal Serial Bus Subsystem (USBSS)
    USB (Universal Serial Bus) provides a low-cost connectivity solution for numerous consumer portable devices by
    implementing a mechanism for data transfer between USB devices.
    The device instantiates two independent instances of a third-party USB subsystem (USB2SS) operating at up
    to USB2.0 speeds (480Mb/s), either of which can be independently configured to act as a USB Host or a USB
    Device.
    For more information, see Universal Serial Bus Subsystem section in Peripherals chapter in the device TRM.

    Regards,
