14 DEVICE CONFIGURATION AND ORDERING INFORMATION
Each device is available for production in user pro-
grammable versions (OTP) as well as in factory
coded versions (ROM). OTP devices are shipped
to customers with a default content (FFh), while
ROM factory coded parts contain the code sup-
plied by the customer. This implies that OTP de-
vices have to be configured by the customer using
the Option Bytes while the ROM devices are facto-
ry-configured.
14.1 OPTION BYTES
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 OTP is fixed
to FFh. This means that all the options have “1” as
their default value.
In masked ROM devices, the option bytes are
fixed in hardware by the ROM code (see option
list).
USER OPTION BYTE
Bit 7:6,4 = Reserved
, must always be 1.
Bit 5 = Reserved
, must always be 0.
Bit 3 = FMP
Full memory protection
This option bit allows the protection of the software
contents against piracy (program or data). When
the protection is activated, read-out of the EPROM
or data EEPROM contents is prevented by hard-
ware.
0: Read-out protection enabled
1: Read-out protection disabled
Bit 2 = Reserved
, must always be 1
Bit 1 = WDG HALT
Watchdog and HALT mode
This option bit determines if a RESET is generated
when entering HALT mode while the Watchdog is
active.
0: No Reset generation when entering Halt mode
1: Reset generation when entering Halt mode
Bit 0 = 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)
