The bit HiAlert is set to logic 1 if maximum WaterLevel bytes (as set in register
WaterLevelReg) or less can be stored in the FIFO-buffer. It is generated according to the
following equation:
The bit LoAlert is set to logic 1 if WaterLevel bytes (as set in register WaterLevelReg) or
less are actually stored in the FIFO-buffer. It is generated according to the following
equation:
