When a rising edge occurs on TI1 (Timer 1), both counters start counting synchronously on
the internal clock and both timers' INT_TIMTIF flags are set.
In this example both timers are initialized before starting by setting their respective TIM_UG
bits. Both counters starts from 0, but an offset can be inserted between them by writing any
of the counter registers (TIMx_CNT). The master/slave mode inserts a delay between
CNT_EN and CK_PSC on Timer 1.

CK_PSC
Configure the Timer 1 in master/slave mode by writing TIM_MSM = 1 (TIM1_SMCR
register).
Configure Timer 2 to get the input trigger from Timer 1 (TIM_TS = 000 in the
TIM2_SMCR register).
Configure Timer 2 in trigger mode (TIM_SMS = 110 in the TIM2_SMCR register).

Internal clock source: connects to STM32W108 peripheral
clock (PCLK) in internal clock mode.
Input to the clock prescaler.
External trigger input (used in external timer mode 2): a clock
selected by TIM_EXTRIGSEL in TIMx_OR.
External trigger: ETRP after filtering.
External trigger: ETR after polarity selection, edge detection
and prescaling.
Input capture or clock: TIy after filtering and edge detection.
