用的是Dspic33ep512GM310，把一些参数写在flash里面保存，写的地址是0x52400，在擦除和写之后，Usart中断就停止工作了，是不是我的擦除函数和写函数有问题，熟悉的帮我看下
uint8 PageErase( uint32 flashAddress )
{
    NVMADR = ( flashAddress & 0xffff );
    NVMADRU = ( (flashAddress >> 16) & 0xffff );
       
    while(NVMCONbits.WR);
    NVMCON = 0x4003;
    __builtin_disi( 6);
    __builtin_write_NVM();
    Nop();
    Nop();
    while(NVMCONbits.WR);
    Nop();
    Nop();
    NVMCONbits.WREN=0;
    Nop();

    if( (NVMCONbits.WRERR == 1) || (NVMCONbits.URERR == 1) )
    {
        return ( WRERR_OR_UERR_ERROR );
    }
    else
    {
        return ( NO_ERROR );
    }
}
uint8  WordWrite( uint32 flashAddress, uint16 ramBuffer1,uint16 ramBuffer2)
{
    // Set up the NVMADR registers to the starting address of the page
    NVMADR = ( flashAddress & 0xFFFF );
    NVMADRU = ( (flashAddress >> 16) & 0xFFFF );
    NVMCON = 0x4001;
    TBLPAG=0xfa;
    __builtin_tblwtl(0x0000,ramBuffer1);//(( flashAddress & 0xFFFF ),ramBuffer);
    __builtin_tblwth(0x0001,0x00);//(( flashAddress & 0xFFFF )+1,0x00);
    __builtin_tblwtl(0x0002,ramBuffer2);
    __builtin_tblwth(0x0003,0x00);
    __builtin_disi( 6);
    __builtin_write_NVM();

    if( (NVMCONbits.WRERR == 1) || (NVMCONbits.URERR == 1) )
    {
        return ( WRERR_OR_UERR_ERROR );
    }
    else
    {
        return ( NO_ERROR );
    }
