43.8.1 Control A

Name: CTRLA
Offset: 0x00
Reset: 0x00
Property: PAC Write-Protection, Write-Synchronized (ENABLE, SWRST)

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

Bit 6 – RUNSTDBY Run in Standby

This bit controls how the TSENS behaves during standby sleep mode:

This bit is not synchronized.

ValueDescription
0 The TSENS is halted during standby sleep mode.
1 The TSENS is not stopped in standby sleep mode. If CTRLC.FREERUN is zero, the TSENS will be running when a peripheral is requesting it. If CTRLC.FREERUN is one, the TSENS will always be running in standby sleep mode.

Bit 1 – ENABLE Enable

Due to synchronization there is delay from writing CTRLA.ENABLE until the peripheral is enabled/disabled. The value written to CTRLA.ENABLE will read back immediately and the ENABLE bit in the Synchronization Busy register (SYNCBUSY.ENABLE) will be set. SYNCBUSY.ENABLE will be cleared when the operation is complete.

This bit is not enable-protected.

ValueDescription
0 The peripheral is disabled.
1 The peripheral is enabled.

Bit 0 – SWRST Software Reset

Writing a zero to this bit has no effect.

Writing a one to this bit resets all registers in the TSENS, except GAIN, OFFSET, CAL and DBGCTRL, to their initial state, and the TSENS will be disabled.

Writing a one to CTRLA.SWRST will always take precedence, meaning that all other writes in the same write-operation will be discarded.

Due to synchronization there is a delay from writing CTRLA.SWRST until the reset is complete. CTRLA.SWRST and SYNCBUSY.SWRST will both be cleared when the reset is complete.

This bit is not enable-protected.

ValueDescription
0 There is no reset operation ongoing.
1 The reset operation is ongoing.
