Register 109H + N*20H, T8TE Interrupt Status
These registers report the interrupt status for T8TE blocks #0 through #11.
FIFOERRI
Bit
Bit 31:5
Bit 4
Bit 3:0
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.
