SEOQandA_Product

question:Why does RX72C4 fail to boot after power-on?
answer:Check clock configuration and startup code. Ensure correct clock source selection and initialization in the reset handler.
question:How to resolve UART communication issues in RX72C4?
answer:Verify pin multiplexing settings, baud rate calculation, and FIFO configuration. Use oscilloscope to validate signal integrity.
question:Why do interrupts not trigger in RX72C4?
answer:Confirm interrupt priority settings, enable global interrupts (CLRPSW I bit), and clear pending flags before enabling interrupts.
question:How to fix memory allocation errors in RX72C4 projects?
answer:Adjust stack/heap sizes in linker script. Use __attribute__((section)) for specific memory placement and validate using memory map files.
question:Why does RX72C4 consume excessive power in sleep mode?
answer:Disable unused peripherals' clocks via MSTP registers, configure I/O pins as outputs, and activate proper low-power mode (SWLLD/SWLLD2).
