I am planning to use ATMEGA324P in my application.
I need to use UART(9600 baud rate) for communication with PC.
1. Is it possible to run UART(baud rate 9600) on internal RC oscillator freq?
2. How to calculate the best calibration value to fit 8 MHz freq with an accuracy of +/- 1%?
3. What should the settling time value?
4. Which peripheral interface ( spi,i2c,adc, etc) of ATMEGA324P would compulsorily require external crystal as clock source?
Thanks in Advance.
