EBV-formatted addressing is best understood by first considering the conversion from an EBV-formatted address to a
standard-formatted address using the following simple rules:
For MaxArias tags up to 16k-bit, 2 bytes are sufficient to address the entire memory. The most significant bit of the
most significant byte is always set to a logic one, while the most significant bit of the least significant byte is always
set to a logic zero.
Given the above addressing conversion, consider the conversion of a standard-formatted address to an EBV-formatted
address:
Several EBV conversion examples are shown below. It should be noted that for Gen2 extended addressing commands,
a 16-bit EBV-formatted address must be used. Address values in the range 0x00 to 0x7F simply have a 0x80
prepended to the address to generate a 16-bit EBV-formatted address. For example, the following addresses are
equivalent:
1. Remove the most significant bits from all bytes.
2. Concatenate the remaining bits.
3. The result is a standard formatted address.
1. Present the standard address as a binary value.
2. Divide the binary address value using a delimiter every 7 bits.
3. Add a flag bit to the most significant bit location for each of the group of 7 bits. The value of the flag bit is
defined as a logic zero for the least significant set of 7 bits and a logic one for all other set(s) of 7 bits.
0x00 = 0x8000
0x01 = 0x8001
0x7F = 0x807F
