9.6.2.5 Synchronization Delay

The synchronization will delay the read/write access duration by a delay D, as shown in the equation below:

5 P GCLK + 2 P APB < D < 6 P GCLK + 3 P APB

Where: P GCLK is the period of the generic clock and P APB is the period of the peripheral bus clock. A normal peripheral bus register access duration is 2 P APB .
