发射端设置了四个不同字节同步码，接收端使用了CC113L 设置两个字节同步码检测，接收端出现了乱码，是什么原因？有相关的接收例程吗？以下是寄存器配置参数：
static const registerSetting_t preferredSettings[]= // should change to CC113L reg
{
{CC113L_IOCFG2, 0x06},
{CC113L_SYNC1, 0x54},
{CC113L_SYNC0, 0x21},
{CC113L_PKTLEN, 0x32},

{CC113L_PKTCTRL0, 0x05}, //

{CC113L_FREQ0, 0x59},
{CC113L_MDMCFG4, 0x2D},
{CC113L_MDMCFG3, 0x3B},
