Data in the ID Tag memory is read by specifying the memory of address and the number of bytes to
process.
Data is written to the ID Tag by specifying the memory address, number of bytes to process, and the
data.
Bits in the ID Tag memory are set by specifying the memory address and number of bytes to process.
Bits in the ID Tag memory are cleared by specifying the memory address and number of bytes to
process.
Based on the specified address, number of blocks to process, and data, the specified memory area of
