R5F21256SNLG#U0 Frequently Asked Questions (FAQ)

  • The recommended power-on sequence is to apply VCC first, followed by VCCIO, and then the clock signal. This ensures proper initialization of the device.

  • The clock settings can be configured using the Clock Control Register (CCR). The CCR allows you to select the clock source, divide the clock frequency, and enable or disable the clock output.

  • The maximum operating frequency of the R5F21256SNLG#U0 is 32 MHz. However, the actual operating frequency may be limited by the system clock source and the clock divider settings.

  • The R5F21256SNLG#U0 has a built-in watchdog timer (WDT) that can be enabled and configured using the Watchdog Timer Control Register (WTCR). The WDT can be used to reset the device in case of a software fault or hang-up.

  • The NMI pin is used to generate a non-maskable interrupt, which is a high-priority interrupt that cannot be masked or disabled by software. The NMI pin is typically used to signal a critical event, such as a power failure or a system fault.
