    Question for GPIF II QD32

    han.xshan

      Hi,

         

      I use GPIF II (master async mode) to access external device, the signals of DQ0-DQ27 are OK, but DQ28-DQ31 is not work! no signal be sent out.  anyone can help me?

         

      here is my init code:

         

          io_cfg.useUart   = CyTrue;
          io_cfg.useI2C    = CyFalse;
          io_cfg.useI2S    = CyFalse;
          io_cfg.useSpi    = CyFalse;

          io_cfg.isDQ32Bit = CyTrue;
          io_cfg.lppMode   = CY_U3P_IO_MATRIX_LPP_DEFAULT;
       

          /* No GPIOs are enabled. */
          io_cfg.gpioSimpleEn[0]  = 0;
          io_cfg.gpioSimpleEn[1]  = 0;
          io_cfg.gpioComplexEn[0] = 0;
          io_cfg.gpioComplexEn[1] = 0;
          status = CyU3PDeviceConfigureIOMatrix (&io_cfg);
