On the WLCSP model of the AD4698, the busy indicator and alert

indicator can be routed to the digital host simultaneously.

Figure 125 shows a simplified connection diagram and software

architecture for utilizing the busy indicator with the alert indicator.

The alert indicator can either feed a separate interrupt service

routine or act as a gate for the busy indicator interrupt service

routine to prevent the SPI from reading from the AD4698 SPI until

the out of bounds condition is met.

The configurations in Figure 124 and Figure 125 are ideal when

operating the AD4697/AD4698 in autocycle mode because it allows

the digital host to be completely idle until an out of bounds condition

occurs and guarantees the digital host can remain synchronized to

the internal conversion timing (see the SPI Peripheral Synchroniza-

tion in Autocycle Mode section).
