Hi Hello,

Operating in single chip mode--> executing application from the internal flash memory, so:

- Hardware setting: Single chip mode is entered, when pin /EA is high during reset.

- Software settings:

* ROMEN bit in SYSCON register must be enabled

* The memory model defines the default variable and function location and their default pointer size. The right selection depends on the application and impacts the compiler efficiency. For more details, please refer to the used toolchain user's manual.

For more details, please refer to the ST10F269 user's manual available on the following link:
