Writing one to the ``FMC_CLK_OE`` field of the ADC core control
register enables the sampling clock (Si570 chip). Also, in order to use
the input offset DACs, the ``OFFSET_DAC_CLR_N`` field must be set to
one.
register enables the sampling clock (Si570 chip), and the other
internal components. Also, in order to use the input offset DACs, the
``OFFSET_DAC_CLR_N`` field must be set to one.
The field ``MAN_BITSLIP`` allows to ’manually’ control the ADC data
alignment in the de-serialiser. When ``TEST_DATA_EN`` is set, the ADC
core writes the address pointer to the memory instead of the ADC
samples. The fields ``TRIG_LED`` and ``ACQ_LED`` allows to control the
FMC front panel LEDs. Those four fields are for test purpose only and
must stay zero in normal operation.
When the sampling clock is enabled, the ``SERDES_PLL`` and
``SERDES_SYNCED`` field from the ADC core status register must be set
alignment in the de-serialiser. The fields ``TRIG_LED`` and
``ACQ_LED`` allows to control the FMC front panel LEDs. Those four
fields are for test purpose only and must stay zero in normal
operation.
When the sampling clock is enabled, check that the ``SERDES_PLL`` and
``SERDES_SYNCED`` fields from the ADC core status register are set
to one.
Calibration values are applied only when the ``CALIB_APPLY`` is set to one.
Before applying this bit, check that the ADC is actually ready for this
operation. You can do this by reading ``CALIB_BUSY``.
