MT9D014 System States
The system states of the MT9D014 are represented as a state diagram in Figure 12 and
described in subsequent sections. The effect of RESET_BAR on the system state and the
configuration of the PLL in the different states are shown in Table 7 on page 29.
The sensor’s operation is broken down into three separate states: hardware standby, soft
standby, and streaming. The transition between these states might take a certain
amount of clock cycles as outlined in Table 7.
