The maximum clock frequency that can be used with the internal oscillator is 16 MHz, but it's recommended to use a maximum of 14 MHz to ensure stability and accuracy.
To configure the watchdog timer to reset the microcontroller, you need to set the WDPG bit in the WWDG_CFR register to select the timeout period, and then enable the watchdog timer by setting the WDV bit in the WWDG_CFR register.
No, the UART in asynchronous mode is limited to a maximum baud rate of 115200 bps. If you need a higher baud rate, you need to use synchronous mode or use an external UART with a higher baud rate capability.
To enable the brown-out reset (BOR) feature, you need to set the BOREN bit in the PWR_CSR register. You also need to configure the voltage threshold by setting the BORV bits in the PWR_CSR register.
No, the I2C interface in master mode is limited to a maximum clock frequency of 400 kHz. If you need a higher clock frequency, you need to use an external I2C controller or a different communication protocol.
