    hi,

    yes you can access to port B in GPIO mode. Configure it in PSDSoft and you have to set correct value in direction and drive registers. You can write and read in port B by the DATA_IN or DATA_OUT register but

    you can't access by bit

    The address for DATAIN_B is: PSD_REG_BASE + 02

    DATAOUT_B: PSD_REG_BASE + 05

    DIRECTION_B: PSD_REG_BASE + 07

    DRIVE_B: PSD_REG_BASE + 09

    CONTROL_B: PSD_REG_BASE + 03
