1. Disable streaming if output is active by setting mode_select = 0 (R0x0100).
2. The soft standby state is reached after the current row or frame, depending on config-
3. Assert hard reset by setting RESET_BAR to a logic “0.”

The digital and analog supply voltages can be powered down in any order. However,
Aptina recommends the following power-down sequence to minimize current
consumption. The power-down sequence corresponds to the requirements described in
section 3.2 of the SMIA functional specification.
The recommended power-down sequence for the MT9D014 is shown in Figure 25 and in
Table 13 on page 53. The available power supplies—V
be turned off at any point or have the separation specified below for reducing current
consumption during power-down sequence.
