1 = always 1; 0 = always 0; d = programmable; ? = read only
AGC/AEC Bin Difference Threshold
Some sensor settings cannot be changed during frame readout. For example, changing
the register Window Width (R0x04) part way through frame readout results in inconsis-
tent LINE_VALID behavior. To avoid this, the MT9V032 double buffers many registers by
implementing a “pending” and a “live” version. Two-wire serial interface reads and
writes access the pending register. The live register controls the sensor operation. The
value in the pending register is transferred to a live register at a fixed point in the frame
timing, called “frame-start.” Frame-start is defined as the point at which the first dark
row is read out. By default, this occurs four row times before FRAME_VALID goes HIGH.
To determine which registers or register fields are double-buffered in this way, see the
“Shadowed” column in Table 8.
