Low-Power Mux
Value | Description |
---|---|
0 | The analog input muxes have low resistance, but consume more power at lower voltages (e.g., are driven by the voltage doubler). |
1 | The analog input muxes have high resistance, but consume less power at lower voltages (e.g., the voltage doubler is disabled). |
Enable
Value | Description |
---|---|
0 | The peripheral is disabled. |
1 | The peripheral is enabled. Each OPAMP must also be enabled individually by the Enable bit in the corresponding OPAMP Control register (OPAMPCTRLx.ENABLE). |
Software Reset
Writing a '0' to this bit has no effect.
Writing a '1' to this bit resets all registers in the MODULE to their initial state, and the OPAMP will be disabled.
Writing a '1' to CTRLA.SWRST will always take precedence, meaning that all other writes in the same write-operation will be discarded.
Value | Description |
---|---|
0 | There is no reset operation ongoing. |
1 | The reset operation is ongoing. |
