15 DEVICE CONFIGURATION AND ORDERING INFORMATION
Each device is available for production in user pro-
grammable versions (FLASH).
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 = PKG Package selection
0: 16-pin package
1: 20-pin package
OPT5:4 = CLKSEL Clock Source Selection
When the internal RC oscillator is not selected
(Option OSC=1), these option bits select the clock
source: resonator oscillator or external clock
Note: When the internal RC oscillator is selected,
the CLKSEL option bits must be kept at their de-
fault value in order to select the 256 clock cycle
delay (see

ST7FLITE1xB devices are shipped to customers
with a default program memory content (FFh).
This implies that FLASH devices have to be con-
figured by the customer using the Option Bytes.
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
tails
0: Read-out protection off
1: Read-out protection on
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.
0: Write protection off
1: Write protection on
