Table 16. Lock Register Bit Definitions
Note: 1. Applies to Top Block Lock Register (T_BLOCK_LK) and Top Block [-1] Lock Register (T_MINUS01_LK) to Top Block [-7] Lock Reg-
ister (T_MINUS07_LK).
Table 17. General Purpose Inputs Register Definition
Note: 1. Applies to the General Purpose Inputs Register (GPI-REG).
Firmware Hub/Low Pin Count (FWH/LPC)
General Purpose Input Register
The FWH/LPC General Purpose Input Register
holds the state of the General Purpose Input pins,
GPI0-GPI4. When this register is read, the state of
these pins is returned. This register is read-only.
Writing to it has no effect.
The signals on the FWH/LPC Interface General
Purpose Input pins should remain constant
throughout the whole Bus Read cycle.
Manufacturer Code Register
Reading the Manufacturer Code Register returns
the value 20h, which is the Manufacturer Code for
STMicroelectronics. This register is read-only.
Writing to it has no effect.

Read-Lock
1
Bus Read operations in this Block always return 00h.
0
Bus read operations in this Block return the Memory Array contents. (Default
value).
1
Lock-Down
1
Changes to the Read-Lock bit and the Write-Lock bit cannot be performed. Once a
1
is written to the Lock-Down bit it cannot be cleared to
0
; the bit is always reset
to
0
following a Reset (using RP or INIT) or after power-up.
0
Read-Lock and Write-Lock can be changed by writing new values to them. (Default
value).
0
Write-Lock
1
Program and Erase operations in this Block will set an error in the Status Register.
The memory contents will not be changed. (Default value).
0
Program and Erase operations in this Block are executed and will modify the Block
contents.
