INTERUPT WHIT ST9 FOR SCI

hello to all,

it is my first post that shipment.

I have a problem with the ST9 F120, I am trying to create a software that to every data received on the serial me kinds a interrupt.

I have connected the ST9 to a hyperterminal I am through SCI1(9,1,9,0), SCI0(5,2,5,1); digit on hyperterminal the SCI0 I would want that it generated a interrupt and that me correspondent to SCI1 wrote the characters on an other hyperterminal but unfortunately this does not happen could even help me with a small code of example? I enclose you mine more soon main and rows SCI.C aspect to yours news thanks

MAIN.C

void main(void)

{

di();

INIT_PLL();

INIT_SCI();

INIT_SCI1();

INIT_SCI_IT();

ei();

spp(P0C_PG);

P0C2R = 0x00;

P0C1R = 0xFF;

P0C0R = 0x00;

P0DR&=0;

while(1)

{

INIT_SCI_IT();

ei();

spp(P0C_PG);

P0DR &= 0x0;

P0DR ^= 0x2;

spp(SCI0_PG);

ToRec=S_RXBR;

if (ToRec != temp)

{

spp(SCI1_PG);

S_TXBR=ToRec;

temp=ToRec;

}

}

spp(P0C_PG);

P0DR ^= 0x80;

}

Hello,

I am sorry, this forum is ST10 related and isn't dedicated to ST9 MCU.

Thank you,

Najoua.
