5.2.1 CHROMAKEY Board Command
// --------------------------------------------------------------------
// Chromakey parameter data types
// hex: 30~3fh => 0~fh
// hex4: [3wh 3xh 3yh 3zh] => w x . y z
// hex6: [3uh 3vh 3wh 3xh 3yh 3zh] => u v / w x / y z
// int: signed integer -100~100 = [80h-100 ~ 80h+100]
// uint: unsigned integer 0~200 = [80h-100 ~ 80h+100]
// int3: signed integer -2048~2047 = [3Xh 3Yh 3Zh] => XYZh

Note: All chromakey parameters will be switched synchronously
with CAM1~4 switching when next frame, UI should be updated
