TUSB3410: There may be a typo in the TUSB3410 datasheet.

Masumi Saito
Intellectual 300 points
Part Number: TUSB3410

Please see the following description of TUSB3410 datasheet.

I think it's a typo. When CONT is "0", pullup disabled. When CONT is "1", pullup enabled.

--------------------------------------------------------------------------------

5.5.5.4 USBCTL: USB Control Register (Addr:FFFCh)

Bit 7 CONT

CONT = 0  Upstream port is connected. Pullup enabled.

CONT = 1  Upstream port is disconnected. Pullup disabled.
