[TYPO] Datasheet: USB device controller IN behavior

[tlyu]

In §4.1.2.6.2 of the RP2040 datasheet (2024-02-02), describing the IN behavior for the USB device controller, this text appears under "TOKEN phase"

if AVAILABLE and FULL bits are set in buffer control move to the phase

The last words should probably be "move to DATA phase".

The entire section could probably use more commas, but that is arguably a style issue.
