Watchdog timers
The watchdog system is based on two independent timers providing maximum security to
the applications.
Window watchdog timer
The window watchdog (WWDG) is used to detect the occurrence of a software fault, usually
generated by external interferences or by unexpected logical conditions, which cause the
application program to abandon its normal sequence.
Independent watchdog timer
The independent watchdog peripheral (IWDG) can be used to resolve processor
malfunctions due to hardware or software failures.
It is clocked by the internal LSI RC clock source, and thus stays active even in case of a
CPU clock failure.
Beeper
The beeper function outputs a signal on the BEEP pin for sound generation. The signal is in
the range of 1, 2 or 4 kHz.
Communication interfaces
SPI
The serial peripheral interface (SPI1) provides half/ full duplex synchronous serial
communication with external devices.
