ADC channel availability depends on part model.

Because ADC12 and ADC13 are shared with the line driver TX pins, a high
level of crosstalk is seen on these pins when used in ADC mode.

Table 36. ADCSTA MMR Bit Designations
Bit Value Description
0 1
Indicates that an ADC conversion is complete.
It is set automatically once an ADC conversion
completes.
0 0
Automatically cleared by reading the
ADCDAT MMR.
Table 37. ADCDAT MMR Bit Designations
Bit Value Description
27:16 Holds the ADC result (see Figure 35).
Table 38. ADCRST MMR Bit Designations
Bit Value Description
0 1
Set to 1 by the user to reset all the ADC
registers to their default values.
