I will be glad when a Context-sensitive spell checker comes out for word. Taped and tapped would never be caught by current spell check. You are right though, the data sheet was in error.
It is very much there and a para consisting of the term under query is quoted below. this extracted frompage 9(above the figure on left side) the datasheet link supplied by the O P.I didn't see the spelling error in the datasheet.
I guess Microchip hires people who are challenged with the English language.
