option bytes. Once the watchdog is activated, it cannot be disabled by the user program
without going through reset.
Window watchdog timer
The window watchdog 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.
The window function can be used to trim the watchdog behavior to match the application
timing perfectly. The application software must refresh the counter before time-out and
during a limited time window. If the counter is refreshed outside this time window, a reset is
issued.
Independent watchdog timer
The independent watchdog peripheral can be used to resolve malfunctions due to hardware
or software failures.
It is clocked by the 128 kHz LSI internal RC clock source, and thus stays active even in case
of a CPU clock failure. If the hardware watchdog feature is enabled through the device
option bits, the watchdog is automatically enabled at power-on, and generates a reset
unless the key register is written by software before the counter reaches the end of count.
5.7.2
Auto-wakeup counter
This counter is used to cyclically wakeup the device in active halt mode. It can be clocked by
the internal 128 kHz internal low-frequency RC oscillator or external clock
5.7.3
Beeper
This function generates a rectangular signal in the range of 1, 2 or 4 kHz which can be
output on a pin. This is useful when audible sounds without interference need to be
generated for use in the application.
5.7.4
Multipurpose and PWM timers
STM8A devices described in this datasheet, contain up to three 16-bit multipurpose and
PWM timers providing nine CAPCOM channels in total. A CAPCOM channel can be used
either as input compare, output compare or PWM channel. These timers are named TIM1,
TIM2 and TIM3.
