Caution
Connect an I/O pin whose input/output mode is unstable to V
DD
via a resistor of several 10 k
(especially if the voltage on the reset input pin rises higher than the low-level input level on power
application or when the mode is switched between input and output by software).
Remark
Because the circuit type numbers shown in the above table are commonly used with all the models in the
78K series, these numbers of some models are not serial (because some circuits are not provided to some
models).
