SRIX4K commands

Figure 47.

Write_block frame exchange between reader and SRIX4K

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.
