Figure 23. Select MCU and Initial Placement of Flash in Code Space or Data Space
Notice that all items compare with the design block diagram. The key items are circled.
Here you can set the parameters if your design and memory map are different. The key items
(fields) for this screen are:
1. Select the MCU. In this case it is STMicroelectronics, then uPSD33xx, then uPSD3334D.
2. Select the main flash memory to reside in 8032 program space at power-up (this means
that the 8032 _PSEN signal is routed to the secondary flash array).
3. Select the secondary flash to reside in 8032 code space at power-up (this means that the
8032 _RD and _WR signals are routed to secondary flash array). Make sure that screen
looks like as shown above.
4. Click OK. Now and then go to the next stepin the Design Flow "Define PSD/Pin/Node
Functions". This is described in detail in the next section.
