15 DEVICE CONFIGURATION
Each device is available for production in user pro-
grammable versions (FLASH) as well as in factory
coded versions (FASTROM).
ST7FLITE2
ST7PLITE2 devices are Factory Advanced Serv-
ice Technique ROM (FASTROM) versions: they
are factory programmed FLASH devices.
ST7FLITE2 devices are shipped to customers with
a default program memory content (FFh), while
FASTROM factory coded parts contain the code
supplied by the customer. This implies that FLASH
devices have to be configured by the customer us-
ing the Option Bytes while the FASTROM devices
are factory configured.
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
OPT7 = Reserved, must always be 1.
OPT6:4 = OSCRANGE[2:0] Oscillator range
When the internal RC oscillator is not selected
(Option OSC=1), these option bits select the range
of the resonator oscillator current source or the ex-
ternal clock source.

Note: When the internal RC oscillator is selected,
the OSCRANGE option bits must be kept at their
default value in order to select the 256 clock cycle
delay (see
OPT3:2 = SEC[1:0] Sector 0 size definition
These option bits indicate the size of sector 0 ac-
cording to the following table.
OPT1 = 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 the ST7 Flash Programming Reference
Manual and

OPT0 = 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.
