Included in the MT9V022 is a register lock (R0xFE) feature that can be used as a solution
to reduce the probability of an inadvertent noise-triggered two-wire serial interface
write to the sensor. All registers (or read mode register—register 13 only) can be locked;
it is important to prevent an inadvertent two-wire serial interface write to register 13 in
automotive applications since this register controls the image orientation and any
unintended flip to an image can cause serious results.
At power-up, the register lock defaults to a value of 0xBEEF, which implies that all
registers are unlocked and any two-wire serial interface writes to the register gets
committed.
If a unique pattern (0xDEAD) to R0xFE is programmed, any subsequent two-wire serial
interface writes to registers (except R0xFE) are NOT committed. Alternatively, if the user
writes a 0xBEEF to the register lock register, all registers are unlocked and any
subsequent two-wire serial interface writes to the register are committed.
If a unique pattern (0xDEAF) to R0xFE is programmed, any subsequent two-wire serial
interface writes to register 13 is NOT committed. Alternatively, if the user writes a
0xBEEF to register lock register, register 13 is unlocked and any subsequent two-wire
serial interface writes to this register is committed.
