•Pins that are to be used for the RC-ADC function must be configured as secondary function input or output
using the mode register (P0MOD0, P0MOD1, P2MOD0, P2MOD1) of the corresponding port.
•All the Port 3 pins except P05/RCM (see Section 24.1.3, “List of Pins”) are configured as pins dedicated to
the RC-ADC function during A/D conversion. Therefore, the Port 0 pins except P05 cannot be used as their
primary functions in oscillation mode No. 0, 1, 2, 3 or 4, which is selected by the RADMOD register. In the
same way, the P20 to P23 pins of Port 2 cannot be used as their primary functions in oscillation mode No. 5, 6
or 7.
