/*

 * The following describes response for the 0x0c query.

 *

 * byte	mask	name			meaning

 * ----	----	-------			------------

 * 1	0x01	adjustable threshold	capacitive button sensitivity

 *					can be adjusted

 * 1	0x02	report max		query 0x0d gives max coord reported

 * 1	0x04	clearpad		sensor is ClearPad product

 * 1	0x08	advanced gesture	not particularly meaningful

 * 1	0x10	clickpad bit 0		1-button ClickPad

 * 1	0x60	multifinger mode	identifies firmware finger counting

 *					(not reporting!) algorithm.

 *					Not particularly meaningful

 * 1	0x80    covered pad		W clipped to 14, 15 == pad mostly covered
