6.5 CRC Validation routines
The following routine calculates CRC using the C language.
Funct_CRC16(unsigned char

crcdata=0xFFFF;
for(i=0;i<DataLen;i++)
{
crcdata=(*puchMsg)^crcdata;
puchMsg++; for(j=0;j<8;j++)
{
tmp=crcdata&0x0001;
crcdata=crcdata>>1;
if(tmp){
crcdata=crcdata^0xA0
01;
}
} }
returncrcdata;
