18 * The alt func groups are the most commonly used functions we place these at
19 * the lower function indexes for convenience, and the less commonly used gpio
20 * functions at higher indexes.
22 * To stay consistent with the datasheet the function names are the same as
23 * the group names for that function's pins
25 * Note - all 1 less than in datasheet because these are zero-indexed
