14 ST72324J/K DEVICE CONFIGURATION AND ORDERING INFORMATION
Each device is available for production in user pro-
grammable versions (FLASH) as well as in factory
coded versions (ROM). FLASH devices are
shipped to customers with a default content (FFh),
while ROM 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 while the ROM devices are
factory-configured.
14.1 FLASH OPTION BYTES
The option bytes allows the hardware configura-
tion of the microcontroller to be selected. They
have no address in the memory map and can be
accessed only in programming mode (for example
using a standard ST7 programming tool). The de-
fault content of the FLASH is fixed to FFh. To pro-
gram directly the FLASH devices using ICP,
FLASH devices are shipped to customers with the
internal RC clock source. In masked ROM devic-
es, the option bytes are fixed in hardware by the
ROM code (see option list).
OPTION BYTE 0
OPT7= 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
OPT6= 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)
OPT5 = CSS
Clock security system on/off
This option bit enables or disables the clock secu-
rity system function (CSS) which include the clock
filter and the backup safe oscillator.
0: CSS enabled
1: CSS disabled
OPT4:3= VD[1:0]
Voltage detection
These option bits enable the voltage detection
block (LVD, and AVD) with a selected threshold for
the LVD and AVD (EVD+IVD).
OPT0= FMP_R
Flash memory read-out protection
This option indicates if the user flash memory is
protected against read-out piracy. This protection
is based on read and a write protection of the
memory in test modes and ICP mode. Erasing the
option bytes when the FMP_R option is selected
induce the whole user memory erasing first.
0: read-out protection enabled
1: read-out protection disabled
