To be connected to VSS0 directly

To be connected to VSS0

To be connected to VDD0

Caution When the I/O mode of an I/O dual-function pin is unpredictable, connect the pin to VDD0 through

a resistor of 10 to 100 kilohms (particularly when the voltage of the reset input pin becomes higher

than that of the low level input at power-on or when I/O is switched by software).

Remark Since type numbers are consistent in the 78K series, those numbers are not always serial in each product.

(Some circuits are not included.)
