See Appendix B for an example Command Response sequence.
AT90RF135602
Response Message
Structure
At the same time as the host sends a message, the AT90RF135602 returns its status
response:
Single byte response from AT90RF135602 = <STATUS>
<CSUM>
If the AT90RF135602 is still busy processing the last command then the response data
received during the 16 clock periods of the polling command message will be:
STATUS = 0x01 which means AT90RF135602 busy.
When the AT90RF135602 has finished its operation, or has error conditions, then either
a single byte or a multi-byte status message will be returned by SPI clocks from the
host.
Multi-byte response from AT90RF135602 =
<STATUS> <STATUS1> <DLV>
<DATA0> <DATA1 ...<CSUM>
Where:
<STATUS> – Status response
<STATUS1> – Status byte 1 which includes further information (e.g. tag type from the
previous operation)
<DLV> – is the length in number of bytes that were successfully read or written (0 to
240). It is only present if relevant to the status response.
<DATAx>
- is data byte(s), if relevant to the command (e.g. for reading)
<CSUM> –
is the 8-bit sum of the proceeding bytes
The message is sent <STATUS> byte first.
The data bytes are sent least significant byte first.
The 8-bit bytes are sent most significant bit first.
0xB4
Write Lock/OTP/User Data Logical to specific UID
(Verify specific UID of tag; if equal then write requested
number of lock, OTP & user data bytes to requested logical
start address of any tag type and verify, if still present)
NB: Writing to UID area is not valid.
<CMD> = 0xB4
<ADR> = Start logical address
<DLV> = Number of bytes to write(n)
<DATA0>…<DATA7> = UID of specified tag
<DATA8>…<DATA7+n> = n bytes to write
<CSUM> = Checksum
UID starts at logical address 0x00 to 0x07
Lock bits start at logical address 0x08 to 0x09
OTP bits start at logical address 0x0A to 0x0F
User data starts at logical address 0x10
<CMD>
