This status register can be read to get updated information on any change in orientation by reading bit 7, or the specifics of the 
orientation by reading the other bits. For further understanding of Portrait Up, Portrait Down, Landscape Left, Landscape Right, 
Back and Front orientations please refer to 

. The interrupt is cleared when reading the PL_STATUS register.

The newlp bit is set to 1 after the first orientation detection after a Standby to Active transition, and whenever a change in lo, bafro, 
or lapo occurs. The newlp bit is cleared anytime the PL_STATUS register is read. lapo, bafro and lo continue to change when 
newlp is set. The current orientation is locked if the absolute value of the acceleration experienced on any of the three axes is 
greater than 1.25 g.
