PSCorrect registers
ADC is used to input ripple data to SDI78. The left channel (7) is used internally. No audio
data can therefore be used on these channels. Though all channel mapping and mixing
from other inputs to channels 7 and 8 internally are still valid.
PSC1-2: ripple correction value (RCV) (0x51, 0x52)
Equivalent to negative maximum ripple peak as a percentage of Vcc (MPR), scaled by the
inverse of maximum ripple p-p as percentage of full-scale analog input to ADC.
Represented as a 1.11 signed fractional number.
PSC3: correction normalization value (CNV) (0x53)
Equivalent to 1 / (1+MPR) expressed as a 0.12 unsigned fractional number.
