Description
Reserved
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.
27.6.3.6 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.
Refer to Conversion Command Format for Alternate Configurations.
ADC0/1 Register Address: 0x30, 0x34, 0x38, 0x3C, 0x40, 0x44, 0x48, 0x4C
