ADC1 – Port C, Bit 1
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
Note:
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 connected between
the AIO outputs shown in the port figure and the digital logic of the TWI module
