• Out of the Port 3 and Port 4 pins, pins that are to be used for the RC-ADC function must be configured as secondary
• All the Port 3 pins except P35/RCM (see Section 24.1.3, “List of Pins”) are configured as pins dedicated to the
In Table 24-1, mode No.0 and mode No.7 are modes where external clocks to be input to the IN0 or IN1 pin are used
for measurement with the RC oscillator circuit stopped.
As shown in Table 24-1, the two oscillator circuits, RCOSC0 and RCOSC1, are so specified that they cannot operate
concurrenty in order to prevent interference in oscillation from occurring when they oscillate concurrently.

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 P44 to P47 pins of Port 4 cannot be used as their primary functions in oscillation mode No. 5, 6
or 7.
