... For example, if five devices are cascaded, in order to perform a write operation to the fifth device, the write-command must be followed by four no-operation commands. When the LOAD/CSN signal goes high, all shift registers are latched. The first four devices will receive no-operation commands and only the fifth device will receive the intended operation command, and subsequently update its register. www.austriamicrosystems.com/LED-Driver-ICs/AS1106_07 D4 D3 ...
