    i have one spi master question

    mekoc_1223776

      I have one question about spi master Read access

      I try to read 256 bytes of data from flash

      all data come out of flash correctly

      but spi madule does not read all the data

      here is my code

       

       

                         SPIM_Flash_Write(0x06);  //Write Enable

                    

                           CyDelay(1000);

           

                          SPIM_Flash_Write(0x03);  //Read data byte

       

                          SPIM_Flash_Write(0x05);  //add 00 Add_Rd_Hi

                          SPIM_Flash_Write(0x01);  //sectR Add_Rd_Lo

                          SPIM_Flash_Write(0x00);

       

       

                         

                      for(j=0; j<240; j++){  //240

                          SPIM_Flash_Write(0x00);  //to generat read clk

                         

                          // SPIM_Flash_ReadArraybl(dbg_array_flashdata,240);  did not work

                          dbg_array_flashdata[j] = SPIM_Flash_Read();// this only read up to 0x7f it does not read the rest
