The functional operating mode of the MT9V012 is controlled by the MODE1 and
MODE0 inputs (Table 2). These inputs should be driven to a static logic 1 or static logic 0
level during normal operation.

Notes: 1. All power supplies should be adequately decoupled.
2. Resistor value 1.5KΩ is recommended, but may be greater for slower two-wire speed.
3. This pull-up resistor is not required if the controller drives a valid logic level on SCLK at all
times.
