R5F21237DFP#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 internal voltage regulators and prevents latch-up.

  • The clock settings can be configured using the Clock Control Register (CCR) and the Clock Source Select Register (CSSR). The CCR sets the clock frequency, while the CSSR selects the clock source (e.g., internal oscillator, external crystal, or external clock).

  • The NMI pin is used to trigger a non-maskable interrupt, which has the highest priority and cannot be masked by software. It is typically used for critical events that require immediate attention, such as a watchdog timer timeout or a power failure.

  • The ADC can be configured using the ADC Control Register (ADCCR) and the ADC Channel Select Register (ADCSR). The ADCCR sets the ADC mode, clock, and trigger, while the ADCSR selects the analog input channel. The ADC conversion result is stored in the ADC Data Register (ADCDR).

  • The maximum operating frequency of the R5F21237DFP#U0 is 32 MHz, but it can be overclocked to 40 MHz with reduced voltage and temperature ranges.
