Failure:
Frame 0x7A 0x01 ErrorCode Checksum
Error Code: Returned status code from tag
Example:
Send: 00 06 00 85 01 01 83
Return: 00 07 01 85 01 C9 1C 57
5.17.4 Read
Function: Read data of the tag
Host sends:
Frame 0x85 0x02 ReadInfo Checksum
ReadInfo: 6 to 9 bytes parameters, depending on byte3 length
ReadInfo
Byte1 MemBank
Memory bank select
00h: Reserved
01h: UII
02h: TID
03h: User
Byte2 WordPtrlength
Length of wordpointer
00h: 8 bit (byte3,WordPtr is 1 byte)
01h: 16 bit (byte3,WordPtr are 2 bytes)
02h: 24 bit (byte3,WordPtr are 3 bytes)
03h: 32 bit (byte3,WordPtr are 4 bytes)
Byte3(Note1) WordPtr Starting address pointer (MSB first)
Byte4 WordCount The number of 16-bit words to be read
Byte5_6 handle 2 bytes handle
Note1: the bytes of this parameter are depending on WordPtrLength. The WrodPtr will be 2
bytes if WordPtrLength equal to 0x02.
Success:
Frame 0x85 0x02 Data Checksum
DATA: n words (16 bits) + handle, data from tag
Failure:
Frame 0x7A 0x02 Error Code Checksum
Error Code: Returned status code from tag
