FIFO_TH_TRIG

RESERVED

FIFO_RESET

[7] FIFO_OFLOW:

Reads 1 if FIFO is overflow

[6] FIFO_FULL:

Reads 1 if FIFO is full

[5] FIFO_EMPTY:

Reads 1 if FIFO is empty

[4] FIFO_TH_TRIG:

0 = Current FIFO size is still below the threshold value

1 = Current FIFO size is at or beyond the threshold value

[3:1] RESERVED

[0] FIFO_RESET:

Write '0' : FIFO put out of reset mode

Write '1' : Resets FIFO. All data in FIFO will be cleared.

When TSC is enabled, FIFO resets automatically.
