This bit is set when there is a FIFO overflow condition. If WCIMODE is set to logic 1, only
over-writing with a ‘1’ clears this bit. If WCIMODE is set to logic 0, then a read of this
register automatically clears the bit.
These bits are used to indicate the FIFO identity. This field should contain the value
“000000”. Otherwise a system error should be declared. These bits are valid only when the
interrupt bit is logic 1.
