15 DEVICE CONFIGURATION AND ORDERING INFORMATION
Each device is available for production in user pro-
grammable versions (FLASH) as well as in factory
coded versions (FASTROM).
ST7PLITE0x and ST7PLITES2/S5 devices are
Factory Advanced Service Technique ROM (FAS-
TROM) versions: they are factory-programmed
XFlash devices.
ST7FLITE0x and ST7FLITES2/S5 XFlash devices
are shipped to customers with a default program
memory content (FFh). The OSC option bit is pro-
grammed to 0 by default.
15.1 OPTION BYTES
The two option bytes allow the hardware configu-
ration of the microcontroller to be selected.
The option bytes can be accessed only in pro-
gramming mode (for example using a standard
ST7 programming tool).
OPTION BYTE 0
Bits 7:4 = Reserved, must always be 1.
Bits 3:2 = SEC[1:0] Sector 0 size definition
These option bits indicate the size of sector 0 ac-
cording to the following table.

vices only.

The FASTROM factory coded parts contain the
code supplied by the customer. This implies that
FLASH devices have to be configured by the cus-
tomer using the Option Bytes while the FASTROM
devices are factory-configured.
Bit 1 = FMP_R Read-out protection
Readout protection, when selected provides a pro-
tection against program memory content extrac-
tion and against write access to Flash memory.
Erasing the option bytes when the FMP_R option
is selected will cause the whole memory to be
erased first, and the device can be reprogrammed.
Refer to
ming Reference Manual for more details.
0: Read-out protection off
1: Read-out protection on
Bit 0 = FMP_W FLASH write protection
This option indicates if the FLASH program mem-
ory is write protected.
Warning: When this option is selected, the pro-
gram memory (and the option bit itself) can never
be erased or programmed again.
0: Write protection off
1: Write protection on
