MIN Luma Value Register
Indirect (Read Only) Register Index 0x0AD
The MIN Luma Value register lets the host or DSP read the minimum pixel value for the Luma component in the unprocessed
data. The Host reads these values through the Host Interface or the DSP receives these values through the serial port.
[15:0]
[31:0]
MAX Luma Value Register
Indirect (Read Only) Register Index 0x0AE
The MAX Luma Value register lets the host or DSP read the maximum pixel value for the Luma component in the unprocessed
data. The Host reads these values through the Host Interface or the DSP receives these values through the serial port.
[15:0]
[31:0]
MIN Cb Value Register
Indirect (Read Only) Register Index 0x0AF
The MIN Cb Value register lets the host or DSP read the minimum pixel value for the Cb component in the unprocessed data.
The Host reads these values through the Host Interface or the DSP receives these values through the serial port.
[15:0]
[31:0]
MAX Cb Value Register
Indirect (Read Only) Register Index 0x0B0
The MAX Cb Value register lets the host or DSP read the maximum pixel value for the Cb component in the unprocessed data.
The Host reads these values through the Host Interface or the DSP receives these values through the serial port.
[15:0]
[31:0]
MIN Cr Value Register
Indirect (Read Only) Register Index 0x0B1
The MIN Cr Value register lets the host or DSP read the minimum pixel value for the Cr component in the unprocessed data.
The Host reads these values through the Host Interface or the DSP receives these values through the serial port.
[15:0]
[31:0]
MAX Cr Value Register
Indirect (Read Only) Register Index 0x0B2
The MAX Cr Value register lets the host or DSP read the maximum pixel value for the Cr component in the unprocessed data.
The Host reads these values through the Host Interface or the DSP receives these values through the serial port.

Bin Width and Reciprocal Bin Width Registers
Indirect (Read/Write) Register Index 0x0100-0x0153
The RBW and BW values are calculated by the host or DSP from data in the Sum of Squares [0-41], Sum of Value, MIN Value, and
MAX Value registers; then are written to RBW and BW registers during encode mode to control the quantizer. The Host writes
these values through the Host Interface or the DSP transmits these values through the serial port.
These registers contain a 16-bit interleaved table of alternating RBW/BW (RBW-even addresses and BW-odd addresses) values
as indexed on writes by address register. Bin Widths are 8.8, unsigned, 16-bit, fixed-point values. Reciprocal Bin Widths are
6.10, unsigned, 16-bit, fixed-point values. Operation of this register is controlled by the host driver or the DSP (84 total entries)
(undefined at reset).
