PRODUCTION DATA
Because CS low is required for communication and SDO can be set to a tri-state condition, only individual CS signals are required from the microcontroller for all the AFEx8101 devices in the system. The SDI, SDO, and SCLK signals can be combined. All the individual ALARM pins can be wired-OR together. This minimizes the number of microcontroller GPIO signals required for communication, as well as the number of isolation channels for isolated systems. The multichannel configuration block diagram is shown in Figure 8-1.
