In Table 21-1, 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 21-1, the two oscillator circuits, RCOSC0 and RCOSC1, are so specified that they cannot operate
concurrently in order to prevent interference in oscillation from occurring when they oscillate concurrently.

Note:
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
function input or output using the mode register (P3MOD0, P4MOD0, P4MOD1) of the corresponding port.
All the Port 3 pins except P35/RCM (see Section 21.1.3, “List of Pins”) are configured as pins dedicated to the RC-ADC
function during A/D conversion. Therefore, all the Port 3 pins except P35 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 P44 to P47 pins of
Port 4 cannot be used as their primary functions in oscillation mode No. 5, 6 or 7.
Figures 21-2 to 24-5 show the oscillator circuit configurations, the modes of oscillation for each configuration, and the
OM3–0 bit settings.
Note:
The unused pin RCT0 shown in Figure 21-2 is configured as a pin dedicated to the RC-ADC function during A/D
conversion; therefore, during A/D conversion, RCT0 cannot be used as a primary function port (P34).
