AVDD

Connect to VDD.

Caution Connect an I/O pin to VDD via a resistor of several 10 kΩ if the I/O mode of the pin is unstable

(especially if the voltage on the reset pin is higher than the low-level input voltage on power application

or if the mode is changed between input and output by software).

Remark The circuit type numbers are common for the 78K series and are not always sequential for one product

(some circuits are not provided).
