STM32 ADC configuration bit field.

• reg (0..0xFF) [ 0 : 7 ]
• shift (0..31) [ 8 : 12 ]
• mask (0x1, 0x3, 0x7) [ 13 : 15 ]
• reg_val (0..7) [ 16 : 18 ]
• real_val (0..8191) [ 19 : 31 ]

Parameters

reg	ADC_x register offset
shift	Position within ADC_x.
mask	Mask for the ADC_x field.
reg_val	Register value (0, 1, ... 7).
real_val	Real corresponding value (0, 1, ... 8191).
