I Input terminal for RC oscillation (when external RC Internal/external

oscillation is used)

Put a resistor between RC1 and RC2, and a capacitor

between RC1 and VSS externally.

Leave open when internal RC oscillation is used.

O Output terminal for RC oscillation (when external RC Internal/external

oscillation is used)

Put a resistor between RC1 and RC2 externally.

Leave open when internal RC oscillation is used.

(Note 1) Nch-OD: N-channel open-drain output

(Note 2) P30INT: Bit 0 of Port 3 interrupt control register (P3INT).

* Port options can be specified for each bit individually.

(Note 3) C1-C32 are the terminal names when 1/32 duty is selected.

C1-C16 and S48-S33 are the terminal names when 1/16 duty is selected.
