* | :----: | :----: | :---- |
* |[15:0] |DACDAT |DAC 12-bit Holding Data
* | | |These bits are written by user software which specifies 12-bit conversion data for DAC output
* | | |The unused bits (DAC_DAT[3:0] in left-alignment mode and DAC_DAT[15:12] in right alignment mode) are ignored by DAC controller hardware.
* | | |12 bit left alignment: user has to load data into DAC_DAT[15:4] bits.

* |[0] |FINISH |DAC Conversion Complete Finish Flag
* | | |0 = DAC is in conversion state.
* | | |1 = DAC conversion finish.
* | | |This bit set to 1 when conversion time counter counts to SETTLET
* | | |It is cleared to 0 when DAC starts a new conversion
* | | |User writes 1 to clear this bit to 0.

* | | |0 = No DMA under-run error condition occurred.
* | | |1 = DMA under-run error condition occurred.
* | | |User writes 1 to clear this bit.

* @var DAC_T::TCTL
* Offset: 0x14 DAC Timing Control Register
* ---------------------------------------------------------------------------------------------------
* |Bits |Field |Descriptions
* | :----: | :----: | :---- |
* |[9:0] |SETTLET |DAC Output Settling Time
* | | |User software needs to write appropriate value to these bits to meet DAC conversion settling time base on PCLK (APB clock) speed.
* | | |For example, DAC controller clock speed is 80MHz and DAC conversion settling time is 1 us, SETTLETvalue must be greater than 0x50.
* | | |SELTTLET = DAC controller clock speed x settling time.

* | :----: | :----: | :---- |
* |[15:0] |DAC0DAT |DAC0 12-bit Holding Data
* | | |These bits are written by user software which specifies 12-bit conversion data for DAC output
* | | |The unused bits (DAC_GRPDAT[3:0] in left-alignment mode and DAC_GRPDAT[15:12] in right alignment mode) are ignored by DAC controller hardware.
* | | |12 bit left alignment: user has to load data into DAC_GRPDAT[15:4] bits.
* | | |12 bit right alignment: user has to load data into DAC_GRPDAT[11:0] bits.
* | | |Note: In group mode, user can write 12-bit conversion data for DAC0 in DAC_GRPDAT[15:0] or DAC0_DAT[15:0]
* | | |The advantage of writing 12-bit conversion data in DAC_GRPDAT[15:0] is that can share one PDMA transfer mechanism.
* | | |Note: Write 12-bit conversion data in DAC0_DAT[15:0] or DAC1_DAT[15:0] have individual PDMA transfer mechanism between two DACs
* |[31:16] |DAC1DAT |DAC1 12-bit Holding Data
* | | |In group mode, user can write these bits for DAC1 12-bit conversion data
* | | |The unused bits (DAC_GRPDAT[3:0] in left-alignment mode and DAC_GRPDAT[15:12] in right alignment mode) are ignored by DAC controller hardware.
* | | |12 bit left alignment: user has to load data into DAC_GRPDAT[15:4] bits.
* | | |12 bit right alignment: user has to load data into DAC_GRPDAT[11:0] bits.
