Flash program memory

3.3.1

Read-out protection

Read-out protection, when selected, provides a protection against Program Memory content

extraction and against write access to Flash memory. Even if no protection can be

considered as totally unbreakable, the feature provides a very high level of protection for a

general purpose microcontroller.

In Flash devices, this protection is removed by reprogramming the option. In this case, the

entire program memory is first automatically erased and the device can be reprogrammed.

Read-out protection selection depends on the device type:

● In Flash devices it is enabled and removed through the FMP_R bit in the option byte.

● In ROM devices it is enabled by mask option specified in the Option List.

ICC interface

ICC (In-Circuit Communication) needs a minimum of four and up to six pins to be connected

to the programming tool (see Figure 7). These pins are:

● RESET: device reset

● VSS: device power supply ground

● ICCCLK: ICC output serial clock pin

● ICCDATA: ICC input/output serial data pin

● ICCSEL/VPP: programming voltage

● OSC1(or OSCIN): main clock input for external source (optional)

● VDD: application board power supply (see Figure 7, Note 3)
