42.1.2 Modes of operation
This module supports the following operation modes.
Table 42-1. Operating modes
Mode Description
Stop and low power stop TSI module is fully functional in all of the stop modes as long
as TSI_GENCS[STPE] is set. The channel specified by
TSI_DATA[TSICH] will be scanned upon the trigger. After
scan finishes, either end-of-scan or out-of-range interrupt can
be selected to bring MCU out of low power modes.
Wait TSI module is fully functional in this mode. When a scan
completes, TSI submits an interrupt request to CPU if the
interrupt is enabled.
Run TSI module is fully functional in this mode. When a scan
completes, TSI submits an interrupt request to CPU if the
interrupt is enabled.
