The Timer Array Unit (TAU0) measures pulse intervals by detecting rising and falling edges on the TI00 input pin, capturing timer counts to determine high-level and low-level pulse widths. Measurements store in on-chip RAM, with interrupts managing edge detection and data capture. The process includes initialization, edge detection, interrupt handling, and data storage, ensuring accurate pulse width measurement. Operation is confirmed on RL78/G22 hardware at 32 MHz, supporting various Renesas development environments. The document details specifications, operation flow, hardware setup, software configuration, and sample code for implementing pulse interval measurement using TAU0 channel 0.

AI 生成的摘要:
The interval timer function of the Timer Array Unit (TAU0) uses timer interrupts (INTTM00) to invert an LED each time the interrupt occurs. The timer interrupt cycle changes based on the number of switch presses, adjusting the LED blinking interval through preset timing values (500 ms to 62.5 ms). The setup includes initializing the timer in interval mode, configuring I/O ports for LED output, and setting external interrupts for switch input detection. The timer counts interrupts and toggles the LED after 250 counts, while switch presses modify the timer interval dynamically.

AI 生成的摘要:
The PWM output function uses timer array unit 0 (TAU0) channels 0 and 1 in simultaneous operation to control LED brightness by varying the duty cycle of PWM pulses. Channel 0 operates as the master timer generating interrupts every 2 ms, counting up to 250 interrupts (500 ms) to trigger duty cycle changes on channel 1, cycling through 10% to 90% duty cycles. LED2 output inverts every 500 ms to indicate duty cycle updates. The PWM output is delivered via the TO01 pin, with the output level set active-low and initial duty cycle at 90%. The program initializes TAU channels, configures I/O ports, and uses HALT mode to wait for timer interrupts, enabling efficient PWM control and LED brightness modulation.

Master transmission and reception using the serial interface IICA in a single-master system enable address transmission, data sending, and receiving with slave devices. The master selects slaves by their 7-bit addresses and communicates with them through data registers. Slave devices have a serial RAM area from 0x80 to 0xFF for data operations, while commands are issued via register 0x00. The communication follows IIC timing protocols, with detailed timing charts and control registers managing start, stop, acknowledge, and data transfer states. The document includes hardware and software configurations, flowcharts, and sample code to implement and verify IICA master communication effectively.

UART communication is implemented using the Serial Array Unit (SAU) on the RL78/G22 microcontroller. The system transmits and receives ASCII characters, analyzing incoming data to generate appropriate responses or error messages. It uses SAU0 channels 0 and 1 with pins P12 (TxD0) and P11 (RxD0), operating at 9600 bps with 8-bit data length, even parity, and LSB first data transfer. Interrupts handle reception, transmission, and errors with low priority. Timing charts illustrate UART transmission and reception processes. The document provides detailed peripheral function settings, operation flowcharts, and sample code to facilitate UART communication implementation.

AI 生成的摘要:
Modbus communication protocol supports data transfer between industrial devices using serial communication modes: Modbus ASCII and Modbus RTU. Modbus operates on a single-master/multi-slave network with up to 247 slaves, each having a unique address. Modbus ASCII transmits data as ASCII characters, increasing data size and transmission time, while Modbus RTU uses binary format for faster communication but requires timing for parsing. The protocol often uses RS-485 physical layer. Combining RL78 microcontrollers with Renesas RS-485 transceivers enables efficient Modbus communication for low-power and I/O control applications. The document details hardware and software configurations, including UART settings, timing intervals, and function codes, to implement Modbus ASCII/RTU communication.
