I have found that if I try to work with UART1 (RS485) I have interrupt
0x0000 000C (Prefetch Abort). (I set a break point to 0x0000 000C)
Is anyone know what mean this interrupt and what that mean?
I have a LPC2294 with 1mb 32bit 0ws external memory. I'm use WinARM
and programm working from internal flash memory.
