    SCLK frequency and Baud rate

    GiCA_4732761

      Hello,

      In the MB9B410T Series datasheet (Document Number: 002-04689 Rev. *E), page 91, concerning CSIO,

                Baud rate = 8 Mbps max

                Serial clock cycle time = 4tCYCP min

                     where "tCYCP indicates the APB bus clock cycle time"

       

      If we consider that tCYCP min = 13.8 ns = 1/72 MHz that makes a maximum of 72/4 =18 Mbps ?

      So why is the maximum specified baud rate 8 Mbps ?

       

      Thanks in advance for your response
