GPIO for clock and detection.
|
|
After reset, the device signals with two falling edges on this pin that it
|
|
is ready for configuration (within 1.2 s).
|
|
During configuration, it is used as clock for data reading and writing (on
|
|
data-gpios).
|
|
After all this, when device is in operational mode, it signals on this pin
|
|
for any detections.

description:

GPIO for data reading and writing. This is denoted "DO (SI)" in datasheet.
|
|
During configuration, this pin is used for writing and reading
|
|
configuration data (together with vout-clk-gpios as clock).
|
|
After this, during operational mode, the device will output serial data on
|
|
this GPIO.
