14.1

Flash device configuration

Each device is available for production in user programmable versions (Flash). Flash

devices are shipped to customers with a default content (FFh) and are configured by the

customer using the option bytes.

lete P 1. Depends on device type as defined in Table 118: Package selection (OPT7) on page 180.

o The option bytes allow the hardware configuration of the microcontroller to be selected.

s They have no address in the memory map and can be accessed only in programming mode

b (for example, using a standard ST7 programming tool). The default content of the Flash is

O fixed to FFh. To program directly the Flash devices using ICP, Flash devices are shipped to

- customers with the internal RC clock source.
