Figure 14. State Machine Transitions––Autonomous Conversion Mode—MAX11800/MAX11801
Autonomous Conversion Mode
The MAX11800/MAX11801 perform measurements
automatically and inform the AP when they are com-
plete in autonomous conversion mode, reducing data
transfers on the serial bus as well as generating fewer
interrupt requests. Figure 14 shows the state machine
transitions for autonomous conversion mode.
