ST72561
14 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/FASTROM).
ST72561 devices are ROM versions. ST72P561
devices are Factory Advanced Service Technique
ROM (FASTROM) versions: They are factory-pro-
grammed HDFlash devices.
ST72F561 FLASH devices are shipped to custom-
ers with a default content (FFh), while ROM facto-
ry 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 ROM devices are factory-config-
ured.
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 a
reserved internal clock source enabled. In masked
ROM devices, the option bytes are fixed in hard-
ware by the ROM code (see option list).
OPTION BYTE 0
OPT7 = WDGHALT 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
OPT6 = WDGSW 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 = Reserved, must be kept at default value.
OPT4 = LVD Voltage detection
This option bit enables the voltage detection block
(LVD).
OPT3 = PLL OFF PLL activation
This option bit activates the PLL which allows mul-
tiplication by two of the main input clock frequency.
The PLL is guaranteed only with an input frequen-
cy between 2 and 4 MHz.
0: PLL x2 enabled
1: PLL x2 disabled
Caution: The PLL can be enabled only if the “OSC
RANGE” (OPT11:10) bits are configured to “MP -
2~4 MHz”. Otherwise, the device functionality is
not guaranteed.
