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 settings can be configured using the Clock Control Register (CCR) and the Clock Source Select Register (CSSR). Refer to the user manual for specific register settings and clock configuration options.
The maximum operating frequency of the R5F51307ADFN#50 is 32 MHz, but it can be overclocked to 40 MHz with reduced voltage and temperature ranges.
The R5F51307ADFN#50 has a built-in watchdog timer that can be enabled and configured using the Watchdog Timer Control Register (WTCR). The watchdog timer can be set to reset the device or generate an interrupt upon timeout.
The minimum operating temperature range is -40°C to 85°C, and the maximum operating temperature range is -40°C to 125°C (with reduced performance and reliability).
