LED burst dimming control uses the logic and event link controller (ELCL) to finely adjust LED brightness by combining two PWM signals with different frequencies. A high-frequency PWM (over 100 kHz) controls current switching, while lower-frequency PWM (~1 kHz) manages overall light intensity without flicker. This method enables precise dimming for LED indicators and lighting. The system configures multiple PWM outputs and uses logical AND operations to generate burst dimming signals for two LEDs simultaneously. The document also provides hardware and software setup details, operation conditions, and sample code for implementation on the RL78/G23 microcontroller.

The RL78/G23 microcomputer uses the SNOOZE mode sequencer (SMS) to monitor the execution of periodic processing by running a timer counter that the CPU must clear regularly. If the CPU fails to clear the counter within a set time, the counter overflows and triggers an interrupt, signaling missed periodic tasks. The SMS timer function supports three channels, each configurable for enable/disable status, compare values to set overflow timing, and counter clearing. External interrupts detect switch inputs and trigger SMS activation. Interrupt requests (INTP1, INTP2, INTP4) handle overflow events, allowing the CPU to respond accordingly. Channels 2 and 3 are optional and require additional interrupt processing if enabled.

The document explains how to use the VBAT pin on the RL78/G23 microcontroller to maintain the real-time clock (RTC) operation during power loss from the main VDD supply. When powered from VDD, the RTC updates the LCD display with clock time via fixed-cycle interrupts. If power switches to VBAT, the RTC continues running but the LCD does not display the time. The voltage detector (LVD0) monitors power source changes and triggers interrupts accordingly. The VBAT pin supplies limited current (max 150 µA) and requires external diodes to prevent backflow. The document details peripheral settings, hardware configuration, and software flow for managing VBAT operation and RTC display.

The frequency detection function compares the high-speed on-chip oscillator clock (HOCO) and the low-speed on-chip oscillator clock (32.768 kHz) to detect abnormal clock frequencies. It measures pulse intervals using timer array unit 0 (TAU0), with HOCO as the count clock and the low-speed oscillator as the timer input. If the frequency is normal, an LED turns off; if abnormal, the LED blinks. The count clock frequency can be dynamically changed via a switch, with LED indicators showing the current clock state. The process involves initializing TAU0, measuring pulse intervals, entering HALT mode, and handling interrupts to verify frequency status or switch clock settings.

视频和培训
This video demonstrates how to debug sketches using the RL78 Arduino library on a Windows PC within the Arduino IDE. Through debugging, developers can collect detailed information from their sketches and observe the internal behavior of the library. The tutorial uses the RL78/G23‑64p Fast Prototyping Board to illustrate the process step by step.
