PWM_INPUT1_TICKS_PER_USEC

#define PWM_INPUT1_TICKS_PER_USEC   6

The default pwm counter is set-up to have 1/6 us resolution.

The timer clock frequency (before prescaling): STM32F1: TIM1 -> APB2 = HCLK = 72MHz TIM2 -> 2 * APB1 = 2 * 36MHz = 72MHz STM32F4: TIM1 -> 2 * APB2 = 2 * 84MHz = 168MHz TIM2 -> 2 * APB1 = 2 * 42MHz = 84MHz
