FIFORST
SCANEN (bit 5)
– Enable ADC channels scan mode.
ADINTE (bit 6)
– Enable interrupt from ADC.
FIFOEN (bit 7)
– Enable FIFO mode when using ADC. If interrupt is enabled, it will occur when TF flag is set
to 1. If this mode is disabled and interrupt from ADC is enabled, it will occur each time on ADC conversion.
Bit FIFORST
– Reset FIFO pointers.

– ADC FIFO status bits: Empty FIFO, FIFO threshold reached, FIFO overflow.
STS (bit 5)
– ADC status: if = 1 the conversion in process or channels scan mode in process.
WAIT (bit 6) = 0
– ADC conversion enabled; = 1 – conversion start is not allowed, the time is needed for
setting a signal when a channel is changed, gain or range is switched. The waiting time is about 10
μs.

DACH0
Bits DACH1-0 set current DAC channel in operation (0 to 3).
Bit DAGEN
– if = 1, write the set data in FIFO along with the channel number.
Bit DASIM
– if = 0, when writing Register 5, the data is transferred to DAC and set at DAC output;
if = 1, write to buffer occurs without output to DAC.
Bit WGINC
– Write the data and increment the address counter in buffer. Manual mode.
Bit WGRST
– Reset the generator buffer address.
Bit WGPS
– Pause the generator. During pause, bit WGRST can be used to reset the generator.
Bit WGSTRT
– Generator start in any mode.
