Table 37 Disabled Outputs to VREF Resistance
A dedicated buffer is available for tying off unused analogue I/O pins as shown in Figure 21. This
buffer can be enabled using the BUFIOEN register bit.
If the SPKBOOST or MONOBOOST 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.
Table 38 summarises the tie-off options for the speaker and mono output pins.
