selected in the option byte, the internal RC is provided. If AWU RC or external clock is
selected, the AWU RC oscillator is provided.
A serial resistor must be connected to I
PA3/RESET 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
PA3 for application reasons.
During normal operation, ICCCLK pin must be pulled- up, internally or externally (external
pull-up of 10 kΩ mandatory in noisy environment). This is to avoid entering I
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.
