Device configuration and ordering information
Each device is available for production in user programmable versions (FLASH) as well as in
factory coded versions (FASTROM). Refer to Table 79 for the full list of supported part
numbers:
●
ST7FLITEUSA2xx and ST7FLITEUSA5xx XFlash devices are shipped to customers
with a default program memory content (FFh).
●
Factory Advanced Service Technique ROM (FASTROM) versions are also available:
they are factory-programmed XFlash devices.
The FASTROM factory coded parts contain the code supplied by the customer. This implies
that FLASH devices have to be configured by the customer using the Option Bytes while the
FASTROM devices are factory-configured.
14.1
Option bytes
The two option bytes allow the hardware configuration of the microcontroller to be selected.
The option bytes can be accessed only in programming mode (for example using a standard
ST7 programming tool).
14.1.1
OPTION BYTE 1
Bit 7:6 CKSEL[1:0] Startup clock selection.
This bit is used to select the startup frequency. By default, the internal RC is
selected (see Table 75: Startup clock selection).
Bit 5 Reserved, must always be 1.
Bit 4 Reserved, must always be 0.
Bits 3:2 LVD[1:0] Low Voltage Detection selection
These option bits enable the LVD block with a selected threshold as shown in
Table 76: LVD threshold configuration.
Bit 1 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)
Bit 0 WDG HALT Watchdog Reset on Halt
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
