{csm_gy_cntl_mult_msb 0x4A(5)} [0]
0 : G/Y data clipping at high end off
1 : G/Y data clipping at high end on
csm_gy_low_clip_on: G/Y low-end clipping on/off
{csm_gy_cntl_mult_msb 0x4A(4)} [0]
0 : G/Y data clipping at low end off
1 : G/Y data clipping at low end on

Numerical format of the CSM mult registers:
The 11-bit value is a binary weighted value in the range 0−1.999.
Thus: csm_mult_<gy,rcr,bcb>(10:0) = [(multiplier in range 0..1.999)/1.999] × 2047.
csm_mult_gy(10:0): G/Y scaling value
{csm_gy_cntl_mult_msb 0x4A(2:0) and [000 0000 0000]
csm_mult_gy_lsb 0x4C(7:0)}
Multiplication factor for G/Y channel in CSM. Range: 0−1.999.
Note: it is possible to scale the input so much that a rollover occurs.
csm_mult_bcb(10:0): B/Cb scaling value
{csm_mult_bcb_rcr_msb 0x4B(6:4) and [000 0000 0000]
csm_mult_bcb_lsb 0x4D(7:0)}
Multiplication factor for B/Cb channel in CSM. Range: 0−1.999.
Note: it is possible to scale the input so much that a rollover occurs.
csm_mult_rcr(10:0): R/Cr scaling value
{csm_mult_bcb_rcr_msb 0x4B(2:0) and [000 0000 0000]
csm_mult_rcr_lsb 0x4E(7:0)}
Multiplication factor for R/Cr channel in CSM. Range: 0−1.999.
Note: it is possible to scale the input so much that a rollover occurs.
csm_mult_rcr_on: R/Cr scaling on/off
{csm_rcr_bcb_cntl 0x4F(7)} [0]
0 : Scaling for R/Cr channel off
1 : Scaling for R/Cr channel on
csm_mult_bcb_on: B/Cb scaling on/off
{csm_rcr_bcb_cntl 0x4F(6)} [0]
0 : Scaling for B/Cb channel of
1 : Scaling for B/Cb channel on
csm_shift_rcr_on: R/Cr shifting on/off
{csm_rcr_bcb_cntl 0x4F(5)} [0]
0 : Shifting for R/Cr channel off
1 : Shifting for R/Cr channel on
