Status1Reg register’s HiAlert bit is set to logic 1 if the remaining
number of bytes in the FIFO buffer space is equal to, or less than the
defined number of WaterLevel[5:0] bits
Status1Reg register’s LoAlert bit is set to logic 1 if equal to, or less
than the WaterLevel[5:0] bits in the FIFO buffer
