15 DEVICE CONFIGURATION AND ORDERING INFORMATION
15.1 INTRODUCTION
Each device is available for production in user pro-
grammable versions (Flash) as well as in factory
coded versions (FASTROM).
The ST7PL0x device is a Factory Advanced Serv-
ice Technique ROM (FASTROM) version: It is a
factory-programmed XFlash device.
The ST7FL0x XFlash device is shipped to custom-
ers with a default program memory content (FFh).
The OSC option bit is programmed to 0 by default.
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.
15.2 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:
Bit 1 = FMP_R Read-out protection
Read-out protection, when selected provides a
protection against program memory content ex-
traction and against write access to Flash memo-
ry. Erasing the option bytes when the FMP_R op-
tion is selected will cause the whole memory to be
erased first, and the device can be reprogrammed.
Refer to Section 4.5 and the ST7 Flash Program-
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 memory
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
