If set, the data stored in FIFO per channel is only 8 bits.

AINT_DATA_SEL

The bit selects data used for APERS calculation.

0 = ASP1 C channel data is used for APERS calculation.

1 = ASP2 C channel data is used for APERS calculation.

2ENAB_RES_BITS

Enable the residue bits.

If enabled, the data format in FIFO is U13.3 that consists

of 13-bit full counts and 3-bit residual counts if DOUBLE_

DATA_MODE is 0. When DOUBLE_DATA_MODE is 1, the

data format in FIFO is U7.1 that consists of 7-bit full

counts and 1-bit residual counts.
