15 DEVICE CONFIGURATION
Each device is available for production in user pro-
grammable versions (FLASH) as well as in factory
coded versions (ROM/FASTROM).
ST7PLITE3 devices are Factory Advanced Serv-
ice Technique ROM (FASTROM) versions: they
are factory programmed FLASH devices.
15.1 FLASH OPTION BYTES
The two option bytes allow the hardware configu-
ration of the microcontroller to be selected.
OPTION BYTE 0
OPT7 = AWUCK Auto Wake Up Clock Selection
0: 32-KHz Oscillator (VLP) selected as AWU clock
.
1: AWU RC Oscillator selected as AWU clock.
Note: If this bit is reset, internal RC oscillator must
be selected (Option OSC=0).
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.
Notes:
1. OSCRANGE[2:0] has no effect when AWUCK
option is set to 0. In this case, the VLP oscillator
range is automatically selected as AWU clock.
2. When the internal RC oscillator is selected, the
OSCRANGE option bits must be kept at their de-
fault value to select the 256 clock cycle delay (see
section 7.5 on page

ST7FLITE3 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.
OPT 3:2 = 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
OPT 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
The option bytes have no address in the memory
map and can be accessed only in programming
mode (for example using a standard ST7 program-
ming tool). The default content of the FLASH is
fixed to FFh.
