STC15+RC523讀卡ID 尋卡直接失敗了，找不到問題點在哪里

RC523已經可以正常讀寫M1卡了，按鍵控制，OLED顯示數據，沒有用串口顯示但是ID讀不出來，第一步尋卡直接失敗了，找不到問題點在哪里，知道的大佬能提點一下。以下是代碼。
單片機源程序如下:

u8 xdata AAA=0;
u8 xdata pUID[10]={0};
void Pcd_Config(u8 type)//寄存器配置
{
PcdAntennaOff();
if ('A' == type)

_nop_();
WriteRawRC(ModeReg,0x3D); //和Mifare卡通訊，CRC初始值0x6363
WriteRawRC(TReloadRegL,30);
WriteRawRC(TReloadRegH,0);
WriteRawRC(TModeReg,0x8D);
WriteRawRC(TPrescalerReg,0x3E);
WriteRawRC(TxAutoReg,0x40);
ClearBitMask(Status2Reg,0x08);
WriteRawRC(ModeReg,0x3D);//3F
WriteRawRC(RxSelReg,0x86);//84
WriteRawRC(RFCfgReg,0x7F); //4F

WriteRawRC(TReloadRegH,0);
WriteRawRC(TModeReg,0x8D);
WriteRawRC(TPrescalerReg,0x3E);
}
else if ('B' == type)
