As shown in
Figure 1, an op amp has an output driver that is directly
connected to an OPnOUT pin. When the output driver for OPn is enabled, the OPnOUT pin
cannot be driven by other peripherals. The output driver can operate in different modes
controlled by the OUTMODE bit field of the OPnCTRLA register. The following output modes
are available:
- OFF - The output driver is
disabled, but can be overridden by a DRIVEn event
- NORMAL - The output driver is
enabled and operates normally
