AI-generated Summary:
The document explains how to control a DC motor-driven button pusher remotely via a network using the RL78/G12 microcontroller and the ESP-WROOM-02 Wi-Fi module. The RL78/G12 obtains an IP address from an access point, connects to a TCP server, and waits for commands. It controls the motor through port outputs and PWM signals to perform normal rotation, stop, and inverse rotation based on received TCP data. The communication uses ASCII-coded packets, and the motor operation timing is adjustable by software. The document also details hardware configuration, software structure, and operation conditions for reliable performance.

AI-generated Summary:
The document explains measuring pulse intervals using the timer array unit channel 0 on the RL78/G12 microcontroller. It details capturing timer counts on pulse edges and storing results in on-chip RAM. The maximum measurable pulse frequency is about 770 kHz, limited by interrupt processing time, while the minimum frequency depends on the 16-bit timer overflow, approximately 92 Hz. Settings allow extending measurement range and accuracy. Operation conditions and related software tools are also specified.
