This bit is set when two SOPs arrive consecutively on the FIFO without being separated by
an EOP. This bit is cleared when read by the user when WCIMODE is set to logic 0. It is
cleared when written to logic 1 when WCIMODE is set to logic 1.
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.
