    Hi,

    Have you set the Port direction register?

    Also, have you correctly set the PSD register address?

    Hello,

    Please see the attached code fragment I wrote to toggle PB0 pin. PB0 is connected to LED2 on the DK3200 eval board. You can just insert the attached code segment to the Main {} loop of the design example 3, dk3200_dsn_3, and complile and download it to a DK3200 board, then watch LED2 blink when Set or Clear PB.0 cmd is issued.
