In making the above register settings, the following restrictions apply,
1. Setting both NDNTSC443(bit 4) and NDPAL60(bit 5) to [1] (High) is prohibited.
2. Setting both ND525L(bit 6) and ND625L(bit 7) to [1] (High) is prohibited.
3. To limit candidate formats, it is necessary to have the auto detection mode OFF while first
setting the register to non-limited signal status and next the NDMODE settings, and then setting
the auto detection mode to ON.
