3.22.2.3 Color Space Conversion Circuit
Note: To access the color space conversion circuit from the CPU, set CMSPCK, CMSHBK, CMSVSY, CMSD[7:0] to

of YUV data has been captured, the color space conversion circuit automatically
converts the data into RGB format.

CMSSCV<CSCVTRG1:0>. A write to the CMSYD/CMSUD/CMSVD register or a write
of 0y1 to the conversion start bit (CMSSCV<CSCVST>) can start conversion. In this
