3.10.2 12-bits Output Resolution
All output data busses are 12-bits in total resolution. Output Y data is always an
unsigned data format. Output Cr Cb is always in a offset binary data format.
Relative to the input data stream the 12-bits outputs are formatted as 10.2 (2 LSB
extensions).
3.10.3 Controllable Rounding and Clipping on Output Data
The GF9330 provides a wide range of round/clipping options based on the setting
of CL_RND[2:0] bits within the host interface as shown in
Table 3-8: CL_RND[2:0]
.
3.11 Sequence Detection
The GF9330 supports two modes of operating with respect to 3:2 sequence
detection (internal and external modes) as described in
Table 3-9: 3:2 Mode Select
.
One bit in the host interface is reserved for the MODE_32 bit.
