This manual introduces the use of 78K/0S series 8-bit single-chip microcontrollers.
This manual is intended for engineers who design and develop applications using the NEC 78K/0S 8‑bit microcontroller series. It covers CPU functions, the full instruction set, detailed instruction descriptions, and hardware design guidelines.
The document also includes safety and handling instructions such as ESD protection, treatment of unused input pins, power‑up initialization procedures, revision history, and contact information for NEC Electronics China. This manual is written in Chinese.

The manual advises using anti‑static containers, grounding work surfaces, wearing a wrist strap, and keeping humidity high to prevent static discharge.
Unused input pins should be tied to VDD or GND with pull‑up or pull‑down resistors, or configured as output pins where possible.
Since the initial state after power‑up is undefined, the device must receive a reset signal before normal operation.
