These registers report the interrupt status for T8TE blocks #0 through #11.

FIFOERRI

The FIFO overrun/underrun error interrupt indication bit (FIFOERRI) reports a FIFO

overrun/underrun error event. FIFOERRI is set high when when FIFO logic detects FIFO

read and write pointers in close proximity to each other. FIFOERRI is cleared on a read to

this register when WCIMODE is logic 0. FIFOERRI is cleared on a write (of any value) to

this register when WCIMODE is logic one. INTB is asserted low when both FIFOERRE and

FIFOERRI are high. IF FIFOERRE is asserted, FIFOERRI must be cleared before INTB will

be reasserted.
