Link_FIFO_OVERFLOW_STAT [7:0]

0
The link FIFO overflow status register reports whether a particular corresponding
link FIFO has experienced an overflow event which occurs when a write
operation is attempted to a full FIFO. Each bit is automatically cleared after a
read operation. If an overflow event occurs the same cycle a read operation
occurs, the set of a status bit overrides the clear operation.
Link FIFO Overflow Status[7:0]
On read, each bit reports the status of the corresponding link FIFO
(1= overflow, 0 = no overflow).
Each set overflow status bit is cleared after a read.
