Parallel Operation of Several ATA6826s
In applications with a high number of loads, parallel operation of the ATA6826 via the microcon-
troller is possible.
Separate control of the ATA6826’s serial peripheral interface is provided by chip select pins CS1
to CS4 (for the function of the serial peripheral interface, please refer to the datasheet).
For simultaneous operation of the serial peripheral interfaces (that is, CS1 through CS4 are
active at the same time), each of the data outputs (DO) needs to communicate with a dedicated
microcontroller input pin.
