Functional Description
Reset sequence
Internal power –on reset (POR)
circuit when power is supplied, and after 1 frame operation is done, all reset sequence is
terminated as all internal registers are loaded to each default value, and sensor is stable.
Therefore, image capturing or chip configuring should be executed on 1 frame time later from
power-on.
External reset
When RESETB pin goes from high to low level, initialization is begun. After 1
frame operation is done, all reset sequence is terminated as all internal registers are loaded to
each default value, and sensor is stable. Therefore, image capturing or chip configuring should be
executed on 1 frame time later from external reset. We recommend initializing sensor by using
RESETB pin before operating it. The condition to reset sensor follow,
1. MCLK is being supplied to sensor.
2. ENB pin is holding '1' and RESETB pin is '1'.
3. RESETB pin have to be keep '0' during minimum 4MCLK periods.
4. After RESETB pin set to '1' and 1 frame time is gone, reset sequence is terminated.

SDA
during the HIGH period of the SCK clock. The HIGH or LOW state of the data line can
only change when the clock signal on the SCK line is LOW. Every byte put on the SDA
line must be 8-bits long. The number of bytes that can be transmitted per transfer is
unrestricted. Each byte has to be followed by an acknowledge bit. Data is transferred with
the most significant bit (MSB) first
.
SDA is the Serial Data line. The data on the SDA line must be stable
Sensor resets automatically by internal power-on reset
Power-down mode
Internal soft power-down
In this mode, all internal digital and analog blocks go into an inactive mode(soft sleep), and power
For entering into soft power-down mode, set SCTRB[4] to '1'.
