static void dmaca_error_int_handler ( void )

static

The DMACA Error interrupt handler.

Note: The `__attribute__((interrupt))' (under GNU GCC for AVR32) and `__interrupt' (under IAR Embedded Workbench for Atmel AVR32) C function attributes are used to manage the `rete' instruction.

static

Initializes the HSB bus matrix.

Referenced by main().

int main ( void )

The main function.

It sets up the USART module on EXAMPLE_USART. The terminal settings are 57600 8N1. Then it sets up the interrupt handler and waits for a USART interrupt to trigger.
