Hi. datasheet says busy pin is bidirectional but it doesn't say anything about how to configure this pin as an input or output. is this auto-sense or I have to manually set this?
/BUSY is a bidirectional pin. There is no need to configure this pin. If an external signal pulls /BUSY low, any writes you make to the AD5360 will not be implemented until /BUSY is allowed to go high. This is useful if multiple AD5360 devices are used. Each will have a slightly different busy time. Connecting all the /BUSYs together will hold off the update of the DACs until the slowest device is ready.
