The Hitag S configuration bytes indicate the type of HS transponder and the mode of

operation. Please note that the MicroRWD H1/S module only supports Plain Memory mode

(default mode as set by Philips). Configuration bytes also control whether the memory blocks

are read/write or locked for read only access.

CON 0 (Read-only – Memory Type information)

CON 1 (Mode and Lock bits)

(CON1 and CON2 access control):

(Page 2 and Page 3 access control)

0 = Read/Write

0 = Read/Write

1 = CON1 read only, CON2 OTP

1 = Read only.

CON 2 (Memory Lock bits)

b7 b6 b5 b4 b3 b2 b1 b0

Lock Page 48 –63 (0 = Read/Write, 1 = Read only)

Lock Page 32 - 47 (0 = Read/Write, 1 = Read only)

Lock Page 24 - 31 (0 = Read/Write, 1 = Read only)

Lock Page 16 - 23 (0 = Read/Write, 1 = Read only)

Lock Page 12 - 15 (0 = Read/Write, 1 = Read only)

Lock Page 8 - 11 (0 = Read/Write, 1 = Read only)

Lock Page 6 - 7 (0 = Read/Write, 1 = Read only)

Lock Page 4 - 5 (0 = Read/Write, 1 = Read only)

Note that CON2 (Memory Lock bits) are OTP (One-Time-Programmable) if LCON = 1

Note also that the “Reserved” bits must not be altered. Page 1 must be read first and the bits

that can be changed masked on/off before writing back.
