Table 4-1. Types of I/O Circuits for Pins and Handling of Unused Pins (2/2)
Caution When the I/O mode of an I/O alternate-function pin is unpredictable, connect the pin to V
DD0
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.)
