The CSU_RSTB signal is a software reset signal that forces the CSU into reset. The CSU is
reset when the CSU_RSTB is logic 0. The CSU is also reset by the NSE-8G master analog
reset signal. When the CSU is reset, the reset signal should be held for at least 100us.
The CSU enable control signal (CSU_ENB) bit forces the CSU into low power configuration.
The CSU is disabled when CSU_ENB is logic one. The CSU is enabled when CSU_ENB is
logic 0.
