PRODUCTION DATA
IN0 to IN23 are inputs connected to external mechanical switches. The switch status of each input, whether open or closed, is indicated by the status registers. Table 8-1 below describes various settings that can be configured for each input. Note some settings are shared between multiple inputs. It is required to first stop device operation by setting the TRIGGER bit low in the register CONFIG before making any configuration changes, as described in Device Trigger.
