9.6.7 Synchronization Delay

Synchronization will delay the duration of read and write access duration by a delay D, as shown in the equation below:

5×PGCLK+2×PAPB<D<6×PGCLK+3×PAPB

Where:

  • PGCLK is the period of the generic clock
  • PAPB is the period of the peripheral bus clock

A normal peripheral bus register access duration is 2×PAPB.
