Name: CTRLA
Offset: 0x00
Reset: 0x00
Property: PAC Write-Protection, Write-Synchronized Bits

Bit 76543210 
  RUNSTDBY    ENABLESWRST 
Access R/WR/WR/W 
Reset 000 

Bit 6 – RUNSTDBY Run in Standby

Note: This bit is not synchronized
ValueDescription
0 The DAC output buffer is disabled in standby sleep mode.
1 The DAC output buffer can be enabled in standby sleep mode.

Bit 1 – ENABLE Enable DAC Controller

Note: This bit is write-synchronized: SYNCBUSY.ENABLE must be checked to ensure the CTRLA.ENABLE synchronization is complete.
ValueDescription
0 The peripheral is disabled or being disabled.
1 The peripheral is enabled or being enabled.

Bit 0 – SWRST Software Reset

Writing '0' to this bit has no effect.

Writing '1' to this bit resets all registers in the DAC to their initial state, and the DAC 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.

Note: This bit is write-synchronized: SYNCBUSY.SWRST must be checked to ensure the CTRLA.SWRST synchronization is complete.
ValueDescription
0 There is no reset operation ongoing.
1 The reset operation is ongoing.
