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.
