V1.2 (TO 30APR2013):

Changed KBI interrupts from edge-sensitive only to edge- and level-sensitive.  This makes
servicing of new data more robust since the fxos8700 device indicates new data using a 
level and not an edge.  In other words fxos8700 is not guaranteed to generate an edge when
new data becomes available which may end up in a deadlock situation with an edge-sensitive
KBI interrupt approach.
