lock_state
byte
0x00 ... 0xFF
Lock state, OTP information:
One bit is used per block (4 x 4 bytes or 2 x 8 bytes)
(bit = 1: block is locked)
Example:
01 = Block 1 of address 0xFF80 ... 0xFF83 is locked or
03 = Block 1 and 2 of address 0xFF80 ... 0xFF87 are
locked,
e.g. for the Philips SL2 ICS20 (MDS D124, D160 or D100).
This chip provides a usable memory with 112 bytes EE‐
PROM from address 0x0000 ... 0x006F (total OTP area
"0x0060 ... 0x006F"). In this memory, the locked area
corresponds to the addresses 0x0060 ... 0x0063 or
0x0060 ... 0x0067
block_size
byte
0x00 ... 0xFF
Block size of the transponder
depending on transponder type, e.g. MDS D3xx: 4 bytes
nr_of_blocks
byte
0x00 ... 0xFF
Number of blocks
depending on transponder type, e.g. MDS D3xx: 248
bytes
