8019K–AVR–11/10
For the assembly code, the baud rate parameter is assumed to be stored in the r17:r16
Registers.
Note:
More advanced initialization routines can be made that include frame format as parameters, dis-
able interrupts and so on. However, many applications use a fixed setting of the baud and
control registers, and for these types of applications the initialization code can be placed directly
in the main routine, or be combined with initialization code for other I/O modules.
Assembly Code Example
C Code Example
USART_Init:
#define FOSC 1843200// Clock Speed

void USART_Init( unsigned int ubrr)
