3. The use of Pin 7 of the ICC connector depends on the programming tool architecture. This pin must be
4. Pin 9 has to be connected to the CLKIN pin of the ST7 when ICC mode is selected with option bytes
5. A serial resistor must be connected to ICC connector pin 6 in order to prevent contention on PA3/RESET
During normal operation, ICCCLK pin must be pulled- up, internally or externally (external
pull-up of 10k mandatory in noisy environment). This is to avoid entering ICC mode
unexpectedly during a reset. In the application, even if the pin is configured as output, any
reset will put it back in input pull-up.
Memory protection
There are two different types of memory protection: readout protection and write/erase
protection which can be applied individually.
Readout protection
Readout 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. Program memory is protected.
In Flash devices, this protection is removed by reprogramming the option. In this case,
program memory is automatically erased, and the device can be reprogrammed.
Readout protection selection depends on the device type:
●
●
Flash write/erase protection
Write/erase protection, when set, makes it impossible to both overwrite and erase program
memory. Its purpose is to provide advanced security to applications and prevent any change
being made to the memory content.
Write/erase protection is enabled through the FMP_W bit in the option byte.
ensure that no external reset is generated by the application during the ICC session.

Please refer to the programming tool manual.
disabled (35-pulse ICC entry mode). When option bytes are enabled (38-pulse ICC entry mode), the
internal RC clock is forced, regardless of the selection in the option byte.
pin. Contention may occur if a tool forces a state on RESET pin while PA3 pin forces the opposite state in
output mode. The resistor value is defined to limit the current below 2 mA at 5 V. If PA3 is used as output
push-pull, then the application must be switched off to allow the tool to take control of the RESET pin
(PA3). To allow the programming tool to drive the RESET pin below V
when a pull-up is placed on PA3 for application reasons.
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.
Warning:
Once set, Write/erase protection can never be removed. A
write-protected flash device is no longer reprogrammable.
