... AN1154 - APPLICATION NOTE APPENDIX E: COMPARING THE DISCRETE AND INTEGRATED SOLUTIONS This appendix compares the two circuits of Figure 2 and Figure 3 in the following categories: Cost Average Current Usage Board Space Usage Time to market (Only the major ICs are compared here.) COST The 150 ns M8813F1x in the PLCC package can be purchased at a significantly lower price than the total cost of the individual EEPROM, Flash, SRAM, and CPLD devices ...

... It is very important to note that the PSD Configuration utility initialises the VM register (located in the CSIOP space at offset E2h), and that it can only be changed by the MCU after it has booted. After the Flash has been programmed or validated, the Flash memory is moved from the 8031 data space to the AN1154 - APPLICATION NOTE 77/83 ...

Figure 62 represents the memory map after the Flash memory has been moved to the program space. This is an intermediate step that is a result of writing to the VM register. ...
