DAC Data Registers (0x180, 0x184, 0x1B0, 0x1B4, 0x1E0, 0x1E4, 0x210 and
0x214)
These registers are intended to be used for DACs operating in Manual Mode (not for Sequencer Mode).
To accelerate data access, each DAC Data Register holds two DAC Channel values.
A write to a DAC Data Register requests the transfer of two digital values to the corresponding DAC (the
DAC Data is transferred to the DAC internal data registers as soon as possible). If not already set because
of ongoing communication with the DAC, the DAC Busy bit in the Global DAC Status Register is set and
remains set until the configuration data transfer to the DAC is done.
For verification after data write the DAC Busy Bit in the Global DAC Status Register should be
monitored whether it was cleared again.
