, for details about the calibration scheme used
in the EQADC.

Alternate Configuration 1-8 Control Registers (ADC_ACR1-8)
The Alternate Configuration Control Registers (ADC_ACR1-8) are used to configure the alternate
configurations of the ADC. There are 8 possible alternate configurations, each one associated with one of
the ADC_ACR1-8 registers. All alternate configurations share the same standard configuration parameters
from the ADC0/1_CR registers, plus additional configuration parameters contained in the ADC_ACR1-8.
A conversion uses one of the alternate configurations when the conversion command (with the alternate
configuration format) is written to an address in the range 0x08-0x0F of the on-chip ADC memory map.

OCC0/1
[0:13]
Offset Calibration Constant of ADC0/1
OCC0/1 contains the offset calibration constant used to fine-tune ADC0/1 conversion
results. Negative values should be expressed using the two’s complement representation.
