The event counter is edge sensitive. After detecting an active edge, a reverse edge
must be detected first before it goes back to the IDLE state and from there starts waiting
for a new active edge.
If the event counter is equal to the value set in the WKUP_COMPARE_REG register,
the counter will be reset, and an interrupt will be generated, if it was enabled by
WKUP_CTRL_REG[ENABLE_IRQ].
The interrupt can be cleared by writing any value to register WKUP_RESET_IRQ_REG.
The event counter can be reset by writing any value to register
WKUP_RESET_CNTR_REG. The value of the event counter can be read at any time
by reading register WKUP_COUNTER_REG.

9.11 General Purpose Timers
The Timer block contains two timer modules that are software controlled, programmable
and can be used for various tasks. Timer 0 is a 16-bit general purpose timer with a
PWM output capability. Timer 2 is a 14-bit counter that generates three identical PWM
signals in a quite flexible manner.
