The interrupt enable register is used to enable the interruption from a system related
interrupt source to the host.

The interrupt status register monitors the status of the interruption from a particular
interrupt source to the host. Regardless of whether the INT_EN bits are enabled, the
INT_STA bits are still updated. Writing '1' to this register clears the corresponding
bits. Writing '0' has no effect.
This bit is set when FIFO level equals to threshold value. It will only be asserted again if FIFO
level drops to < threshold value, and increased back to threshold value.
