Via 8-bit SPI for all the outputs
Control data are transmitted to SDI through a microcontroller in configuration master. The
device is selected when NCS signal is low. The 8-bit command data are transmitted into
L9826 shift registers every CLK falling edge (see
The NCS rising edge latches the new data from the shift register to the driver and the output
are driven following the commands just sent.
The digital filter between NCS and the output latch ensures that the data are transferred
only after 8 CLK cycles or multiple of 8 CLK cycles since the last NCS falling edge.
The NCS changes only at low CLK.
