PC1 can also be used as ADC input Channel 1. Note that ADC input channel 1 uses
analog power.
• ADC0 – Port C, Bit 0
PC0 can also be used as ADC input Channel 0. Note that ADC input channel 0 uses
analog power.
Table 26 and Table 27 relate the alternate functions of Port C to the overriding signals
shown in Figure 25 on page 54.

1. When enabled, the Two-wire Serial Interface enables slew-rate controls on the output
pins PC4 and PC5. This is not shown in the figure. In addition, spike filters are con-
nected between the AIO outputs shown in the port figure and the digital logic of the
TWI module.
