Program operation automatically verifies the programmed data by reading back the programmed data and checking it against the buffer sent to the target device The Verify operation is much more secure but slower since it reads back the programmed data and checks it against the data buffer present in the host PC Page 32 PK HCS12C32 User s Manual In case of verifying error please verify the value programmed to the FLASH Options Security Byte location The bit 0 of this byte is always programmed to 0 so any attempt to program it to 1 will cause a verifying error In the Auto operation a Run option is available which if enabled resets the microcontroller and runs the user application at the end of programming Page 33 PK HCS12C32 User s Manual 5 Troubleshooting Common Problems and Solutions This section reports some common problems that may arise during general use Communication Can t Be Established with PK HCS12C32 1 2 Make sure the PK HCS12C32 starter kit is connected to the PC and powered on PK HCS12C32 is powered by the USB connection If you connected the PK HCS12C32 board to the PC before installing the CodeWarrior user interface and the SofTec Microsystems Additional Components the PK HCS12C32 USB driver may not have been correctly installed on your system Unplugging and replugging the USB cable is of no use since Windows has marked the device as disabled As a co
