Sel_P15(1), (2)

1. Not available on the STLUX285A; these bits are set to 1 after reset, must be cleared by SW during the IC

device initialization phase and during register write operations.

2. Not available on the STLUX325A; these bits are set to 1 after reset, must be cleared by SW during the IC

device initialization phase and during register write operations.
