A dedicated buffer is available for tying off unused analogue I/O pins as shown in Figure 22. This
buffer can be enabled using the BUFIOEN register bit.
If the SPKBOOST, OUT3BOOST or OUT4BOOST bits are set then the relevant outputs will be tied
to the output of the DC level shift buffer at 1.5xAVDD/2 when disabled.
Figure 22 summarises the tie-off options for the speaker and mono output pins.
