外部4M晶振
main() {
SCPSC = 0x48;
SCBR = 0x01;
SCC1_ENSCI = 1;
SCC1 = 0;
SCC2 = 0;
SCC2_TE = TRUE;
SCC2_RE = 1;
SCC3 = 0;
SCC2_SCRIE = TRUE;
SCC2_TCIE = TRUE;
SCC2_SCTIE = 0;
SCC2_SCRIE = TRUE;
EnableInterrupts;
for(;;){
while(!SCS1_SCTE);
SCDR = 0X55;
Delay(200);//延时
PTE_PTE5 = ~PTE_PTE5;
Delay(200);//延时
}
}
程序运行后,PTE5脚有脉冲输出,但是TXD脚没有反应,一直高电平.
不知道初始化中那里错了(PLL已经初始化)
