MT9M019 System States
The system states of the MT9M019 are represented as a state diagram in Figure 11 and
described in subsequent sections. The effect of RESET_N on the system state and the
configuration of the PLL in the different states are shown in Table 6.
The sensor’s operation is broken down into three separate states: Hardware standby,
software standby, and streaming. The transition between these states might take a
certain amount of clock cycles, as outlined in Table 6.
