Input
Input
Master input clock (27MHz): This can either be a square-wave generated from an
oscillator (in which case the XTAL input must be left unconnected) or connected
directly to a crystal.
If EXTCLK is connected to one pin of a crystal, this signal is connected to the other pin;
otherwise this signal must be left unconnected.
Asynchronous active-low reset: When asserted, the device will return all interfaces to
their reset state. When released, the device will initiate the boot sequence. This signal
has an internal pull-up resistor.
This input can be used to set the output timing of the ASX340CS to a fixed point in the
frame.
The input buffer associated with this input is permanently enabled. This signal must
be connected to GND if not used.
Register Interface

Input/Output
Input
These two signals implement serial communications protocol for access to the internal
registers and variables.
This signal controls the device ID that will respond to serial communication
commands.

Input/Output
Pixel data from the ASX340CS can be routed out on this interface and processed
externally.
To save power, these signals are driven to a constant logic level unless the parallel pixel
data output or alternate (GPIO) function is enabled for these pins. For more
information see Table 16 on page 35.
This interface is disabled by default.
The slew rate of these outputs is programmable.
These signals can also be used as general purpose input/outputs.
When the sensor core is running in bypass mode, it will generate 10 bits of output data
per pixel. These two pins make the two LSB of pixel data available externally. Leave
DOUT_LSB1 unconnected if not used. To save power, these signals are driven to a
constant logic level unless the sensor core is running in bypass mode or the alternate
function is enabled for these pins. For more information see Table 16, “GPIO Host
Commands,” on page 35. The slew rate of these outputs is programmable.
