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.

LCON bit
(CON1 and CON2 access control):
0 = Read/Write
1 = CON1 read only, CON2 OTP
LKP bit
(Page 2 and Page 3 access control)
0 = Read/Write
1 = Read only.
CON 2 (Memory Lock bits)

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.
