Device configuration and ordering information
Each device is available for production in user programmable versions (Flash) as well as in
factory coded versions (ROM/FASTROM).
ST72324B-Auto devices are ROM versions. ST72P324B-Auto devices are Factory
Advanced Service Technique ROM (FASTROM) versions: They are factory-programmed
HDFlash devices. 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 using the Option bytes while the ROM
devices are factory-configured.
Flash devices
Flash configuration
The option bytes allow the hardware configuration 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 default content of the Flash is
fixed to FFh. To program directly the Flash devices using ICP, Flash devices are shipped to
customers with the internal RC clock source. In masked ROM devices, the option bytes are
fixed in hardware by the ROM code (see option list).
