SOPI
SOPI:
This bit is set when two SOPs arrive consecutively on the FIFO without being separated by a
EOP. This bit is cleared when read by the user.
SOP_FIFO[5:0]:
These bits are used to indicate the FIFO identity. This field should contain the same number
as the FIFO_NUMBER [5:0] field in RXSDQ FIFO Indirect Configuration register; otherwise,
an system error should be declared. These bits are valid only when the interrupt bit is logic 1.
