bits)

This register sets up the polarity of the external MOSFET controller outputs upon actuation

and can actuate these drivers as in register 00H. These values will remain in this register

even after actuation.

This register can be read or written. New data is not acted upon if programmed while in

timed actuation. New data will be used in subsequent timed actuations.
