Apply Power
Observe the following procedure to complete your hardware connection to the Z8051
USB OCD interface.
1. Ensure that the power is off to the target MCU and that the MCU is soldered properly
onto the target board.
If your target MCU is already powered on prior to connecting the USB OCD interface,
it may not be able to recognize which mode the OCD is operating in. The target MCU is
identified at power-up whether it is in OCD or User Mode.
2. Power on your PC.
3. Connect the OCD hardware to your PC.
4. Connect the OCD hardware to your target system.
5. Apply power to the target system.
6. Use the OCD In-System Programmer to perform your programming tasks.
7. When your programming work is complete, power off the target system.
Understanding the OCD ISP Menu Functions
This section describes the operation of the HexData, Program, Window and Child menus.
HexData Menu
The HexData menu, shown in Figure 76, allows users to load their hexadecimal code to a
target device for programming. Because each device operates on its own programming
algorithm and features a different memory map, ISP functions are enabled only after a tar-
get device has been selected.
