Device configuration and ordering information
Each device is available for production in user programmable versions (High Density
FLASH).
ST72F63B FLASH devices are shipped to customers with a default content (FFh).
This implies that FLASH devices have to be configured by the customer using the Option
Byte while the ROM devices are factory-configured.
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 using a standard ST7 programming tool. The default contents of the
FLASH is fixed to F7h. This means that all the options have “1” as their default value, except
LVD.
In ROM devices, the Option Byte is fixed in hardware by the ROM code.

OPT 7:6 Reserved
OPT 5 WDGSW Hardware or Software Watchdog
OPT 4 WDHALT Watchdog and Halt mode
OPT 3 LVD Low voltage detector selection
--
This option bit selects the watchdog type.
0: Hardware enabled
1: Software enabled
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
This option bit selects the LVD.
0: LVD enabled
1: LVD disabled
Note: Important: on ST7263BK1M1, ST7263BK2M1, ST7263BK2B1, and
ST7263BK2B1 ROM devices, this option bit is forced by ST to 0 (LVD
always enabled).
