Rb/Ra is the V0 voltage regulator internal resistor ratio and can be set to 8 different levels
through the V0 voltage regulator internal resistor ratio set command. The (1+Rb/Ra) ratio
assumes the values shown in Table 8 depending on the 3-bit data settings in the V0 voltage
regulator internal resistor ratio register.
