Hi,
"For interrupt driven USART operation, the Global Interrupt Flag should be cleared (and interrupts globally disabled) when doing the initialization." I don't understand the topics why it is necessary to clear interrupt flag. If anyone deal with this matter pls provide the clarification and if possible provide necessary links or pdf.
