INPUT MIXER ENABLE
The WM8962 has two analogue input mixers, which provide mixing and signal boost functions for the
analogue input paths.
The input mixers MIXINL and MIXINR are enabled by the MIXINL_ENA and MIXINR_ENA register
bits, as described in Table 9. Note that the input mixers can also be controlled by INL_ENA and
INR_ENA, as described in Table 5.
