The SMIA specification imposes a number of programming restrictions. An implemen-
tation naturally imposes additional restrictions. Table 5 shows a list of programming
rules that must be adhered to for correct operation of the MT9M019. It is recommended
that these rules are encoded into the device driver stack, either implicitly or explicitly.
