Clock output

System clock oscillation crystal/ceramic connection pin.

—

When an external clock is used, the clock is input to X1

and the inverted clock is input to X2.

—

System reset input (low-level active).

—

Internally Connected. IC pin should be connected to VDD

directly.

—

Positive power supply.
