FUNCTION
Open-Drain Output That Asserts Low During a Number of Different Error
Conditions. The cause of the error is latched in the FLAGS register. See Diagnostic
and Fault Reporting Features for details on clearing FAULT.
Digital Comparator Output. COUT is high when AIN is above the upper threshold
(THU) and low when AIN is below the lower threshold (THL).
Chip Select for SPI Interface. Assert low to enable SPI functions and SDO. SDO is
high impedance when CS is high.
Serial Clock for SPI Interface
Serial Data Input for SPI Interface (MOSI)
Serial Data Out for SPI Interface (MISO)
