要求串口能收發，波特率4800bps，工作於方式1，采用中斷方式發送或者接收數據，試編寫壹段串口初始化的子

void InitUART(void)

{

TMOD = 0x20;

SCON = 0x50;

TH1 = 0xFA;

TL1 = TH1;

PCON = 0x00;

EA = 1;

ES = 1;

TR1 = 1;

}

void SendOneByte(unsigned char c)

{

SBUF = c;

while(!TI);

TI = 0;

}

void main(void)

{

InitUART();

while(1)

{

}

}

void UARTInterrupt(void) interrupt 4

{

if(RI)

{

RI = 0;

//add your code here!

}

else

TI = 0;

}
