[OTG + documentation] global NAK clear

More.

The description of global NAKclearing for both IN and OUT is a mess reoccurring in several places - in the description of four set/clear bits in DCTL, in the narrative in several subchapters of Operational model chapter, in description of GONAKEFF/GINAKEFF in GINTSTS. Sometimes they are said to be cleared by 'writing to CGxNAK' (which should probably read as 'writing 1 to CGxNAK' - all four bits in DCTL are probably 'read 0, write 0 ignored, write 1 causes action'), sometimes by 'clearing CGxNAK', sometimes by 'clearing SGxNAK'. There is a bizarre mess at one point in the Operational model chapter, where the text calls for ' clear the SGONAK bit in OTG_FS_DCTL', and pseudocode below that reads 'OTG_FS_DCTL = 1 in CGONAK'...

Seriously?

To clear/set the Global IN/OUT NAK, writing '1' in the CGXNAK/SGONAK is needed.

This precision will be added to the description of those bits on the reference manual.

In RM0090, GONAKEFF (a OTG_FS_GINTSTS bit) is in two instances misspelled as GOUTNAKEFF.

Hi Jan,

This issue was already reported and will be fixed on next versions of the reference manuals.

Many thanks.

Khouloud.
