单片机是PIC24FJ256GB206

配置位如下：

// These are the same config settings used by the bootloader and must not be changed here.
_CONFIG1( JTAGEN_OFF & GCP_OFF & GWRP_OFF & FWDTEN_OFF & ICS_PGx3)
_CONFIG2( IESO_OFF & FCKSM_CSDCMD & OSCIOFNC_OFF & POSCMOD_NONE & FNOSC_FRCPLL & PLLDIV_NODIV & IOL1WAY_ON)
_CONFIG3( SOSCSEL_EC & WPCFG_WPCFGDIS & WPDIS_WPDIS)                //Disable erase/write protect of all memory regions.

擦除代码用的官方的：

void Erase(WORD page, WORD addrLo, WORD cmd)
{
        WORD temp;       

        temp = TBLPAG;
        TBLPAG = page;

        NVMCON = cmd;

        __builtin_tblwtl(addrLo,addrLo);

        __builtin_write_NVM();

        while(NVMCONbits.WR == 1);

        TBLPAG = temp;
}

为何执行Erase(170, 0, PM_PAGE_ERASE);后，串口就收不到数据了？如果执行了该操作，重新初始化串口，则又可以收到数据。
