15 DEVICE CONFIGURATION AND ORDERING INFORMATION
Each device is available for production in user pro-
grammable versions (FLASH). FLASH devices are
shipped to customers with a default content (FFh).
This implies that FLASH devices have to be con-
figured by the customer using the Option Bytes.
15.1 OPTION BYTE
The option byte allows the hardware configuration
of the microcontroller to be selected.
The option byte has 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. This means that all the options have
“1” as their default value.
OPT7 = Reserved. Must be kept at 1.
OPT6 = PE5PU I/O Port PE5 Pull-up Option
This option bit determines if a pull-up is connected
on Port E5.
0: Pull up present on PE5
1: No pull-up on PE5
When PE5PU=00, (also refer to
– For input, software can enable or disable the
– For output, the pull-up is enabled when Open
pull-up by programming PEOR.5 and PED-
DR.5=0.
Drain is selected by programming PEOR.5= and
PEDDR.5=1.

OPT5:4 = PSMOD[1:0] Power Supply Mode
These option bits configure the power supply
mode. Refer to
Table 39. Power supply bits
OPT3 = Reserved. Must be kept at 1.
OPT2= WDG SW Hardware or software watchdog
This option bit selects the watchdog type.
0: Hardware (watchdog always enabled)
1: Software (watchdog to be enabled by software)
OPT1 = USBEN
0: USBEN alternate function disabled. Port F4 is
1: USBEN alternate function enabled on Port F4
OPT0= FMP_R Flash memory read-out protection
Readout protection, when selected provides a pro-
tection against program memory content extrac-
tion and against write access to Flash memory.
This protection is based on read and a write pro-
tection of the memory in test modes and IAP.
