FTH

FIFO threshold status.

(0: FIFO filling is lower than FTH level; 1: FIFO filling is equal to or higher than

threshold level)

OVR

FIFO overrun status. (0: FIFO is not completely filled; 1: FIFO is completely filled

and at least one sample has been overwritten)

DIFF8

Concatenated with FIFO_SAMPLES_A (30h) register, it represents the number of

unread samples stored in FIFO. (000000000 = FIFO empty; 100000000 = FIFO

full, 256 unread samples).

DIFF [7:0]

Concatenated with DIFF8 bit in FIFO_SRC_A (2Fh) register, it represents the

number of unread samples stored in FIFO. (000000000 = FIFO empty;

100000000 = FIFO full, 256 unread samples).
