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?
