slave mode routine:
TIM1_CH1(PA8)
This example demonstrates that when the TIM_CH1(PA8) pin detects a rising edge, TIM1 works
differently in different slave modes.
RESET_MODE: TIM1->CNT reset and recount
GATED_MODE: PA8 pin input low level, TIM1->CNT counts normally, otherwise stop counting.
TRIGGER__MODE: TIM1->CNT continues counting.
