DA1468x USB Function

Hi support !

1)
Does DA1468x support USB1.1 or USB2.0?

In the datasheet(rev. 2.1), it has been described as a "USB1.1".
On the other hand, in the another documents
(dialog-smartbond-da14680-product-brief-japanese.pdf ,
dialog-smartbond-da14680-product-brief-tcn.pdf , and
Roadmap[ Dialog SmartBond Introduction(page 14)] )
it has been described as a "USB2.0"

The description of "USB1.1" is correct, I think.

2)
Using this USB I/F, is it possible to access(read/write) the data area,
such like as Flash memory area(da14680) and Ext-flash memory area(da14681) ?

Best regards,
