Hello,
I saw it, but i was confused as it showed no name of UBRRL and UBRRH registers. SO read it again, found little solution. WIll try it. Sorry for my lame understanding.Somehow GPS module stopped working now. It is my first time working with GPS and AVR so cleared the doubt by asking experienced people here.
You obviously didn't read the datasheet.
This is what it says:
"This is a 12-bit register which contains the USART baud rate. The UBRRH contains the four
most significant bits, and the UBRRL contains the eight least significant bits of the USART baud
rate. Ongoing transmissions by the Transmitter and Receiver will be corrupted if the baud rate is
changed. Writing UBRRL will trigger an immediate update of the baud rate prescaler."
Additionally there us a picture about both registers where you can see each single bit and it's function."
I expect a little effort on your own. This is why I will leave this thread.
