//Verify section 4 key with 0 model
unsigned char password[7]={0xa0,0xa1,0xa2,0xa3,0xa4,0xa5};
if((fw_authentication_pass(icdev,0,4,password))!=0)

int fw_read(int icdev,unsigned char _Adr,unsigned char *_Data);
Description
Read content of card.
For M1 card :Read one block data(16 bytes) once.
For ML card:Read two pages with same property once (0 and 1,2 and 3 ,...), 8
bytes.
Parameters

_Adr:M1 Card——Address of block M1（0～63）,MS70(0-255)；
_Data:[out] data of card.

Example
int st;
unsigned char data[16];
st=fw_read(icdev,4,data); //Read block 4 of M1 card
Related HEX function:
int fw_read_hex(int icdev,unsigned char _Adr,char *_Data)
Remark
the difference between HEX function and normal function is, the string of HEX
function is in the form of hex, while the string of the corresponding normal function
is in the form of ASC codes. For example, if the actual data of second block is:
"1234567890abcedf", then called function fw_read_hex will return the string:
