hello,
I have to communicate USART in P18F4550 micro controller in high baud rate mode. According to pic18f4550 datasheet their is a BRGH bit in a TXSTA register, using this bit we can enable the high speed baud rate. but when i calculate the baud rate value for high speed baud rate mode then the value calculated is more then 8 bit which is greater than the size of SPBRG register. I am using 48 MHZ Chrystel Oscillator for PIC. So please suggest me the way of communicate with the high speed baud rate using PIC18F4550.
Thank you
