Note:
Serial communication format (transmission)
The figure below shows the “transmission” from STLED316S for data read sequence.
Figure 6.
Because the DIN/DOUT pin in a bi-directional pin, it is recommended to connect an external
pull-up resistor to this pin (1 KΩ to 10 KΩ).
No minimum wait time is needed to read the data from the device. The STLED316S will
output the data about 250 ns after the 8
that the host must release the bus within 100ns after clocking the last bit on the 8
pulse. The STLED316S is able to clock out the valid data on the immediate falling edge of
the CLK without missing any clock cycle.
