R5F2123AJFP#U0 Frequently Asked Questions (FAQ)

  • The recommended power-on sequence is to apply VCC first, followed by VDD, and then the clock signal. This ensures that the internal voltage regulators and clock circuitry are properly initialized.

  • The clock source can be configured using the Clock Control Register (CCR). The CCR register allows you to select between the internal high-speed oscillator, external clock, or low-power oscillator. You can also configure the clock frequency and divider settings using this register.

  • The maximum operating frequency of the R5F2123AJFP#U0 is 32 MHz. However, the actual operating frequency may be limited by the clock source and the system clock divider settings.

  • The watchdog timer can be enabled and configured using the Watchdog Timer Control Register (WTCR). You can set the watchdog timer period, enable or disable the timer, and configure the timer mode using this register. The watchdog timer can be used to reset the microcontroller in case of a software or hardware fault.

  • The NMI pin is used to generate a non-maskable interrupt, which can be used to signal a critical event or error condition to the microcontroller. The NMI interrupt has the highest priority and cannot be masked or disabled by software.
