Action Bit
0
This bit is an action bit. The value of this bit is written to
any selected bits during register writes. Bits to be written
are selected by placing a 1 in each desired location as
the register is written. Any bit positions that contain a 0
during register writes remain unchanged.
This bit always reads back as 0.
