GET_UID() command

Command Code = 0Bh

On receiving the GET_UID command, the SRIX4K returns its 8 UID Bytes. UID Bytes are

transmitted with the Least Significant Byte first, and each byte is transmitted with the least

significant bit first.

The SRIX4K must have received a SELECT() command and be switched to SELECTED

state before any GET_UID() command can be accepted. All GET_UID() commands sent to

the SRIX4K before a SELECT() command is issued, are ignored.
