 Does anyone know if I can assume that for every SAR_RANGE_INTR bit that is asserted it will happen at the same time that the SAR_EOS_INTR bit is asserted?

Hello Michael,

In SAR ADC after completing a scan, the end-of-scan interrupt (EOS_INTR) is raised, where as range detection interrupt flag can be set after averaging, alignment, and sign extension (if applicable). This means it is not required to wait for the entire scan to complete to determine whether a channel conversion is over-range. These details are available on architectural TRM , http://www.cypress.com/file/126171/download
