XYCOM XVME-689 Semiconductor module

The entire user’s program memory can be assigned to FPP0 when single FPP mode is selected. Table 3 shows the example of program memory using for single FPP unit mode.

Program structure of two FPP units mode 

After power-up, the program starting address of FPP0 is 0x000 and 0x001 for FPP1. The 0x010 is the entry address of interrupt service routine, which belongs to FPP0 only. The basic firmware structure for PMC234/PMS234 is shown as Fig. 4, the program codes of two FPP units are placed in one whole program space. Except for the initial addresses of processing units and entry address of interrupt, the memory location is not specially specified; the program codes of processing unit can be resided at any location no matter what the processing unit is. After power-up, the fpp0Boot will be executed first, which will include the system initialization and other FPP units enabled.

Program structure of single FPP mode

 After power-up, the program starting address of FPP0 is 0x000, 0x010 is the entry address of interrupt service routine. For single FPP unit mode, the firmware structure is same as traditional MCU. After powerup, the program will be executed from address 0x000, then continuing the program sequence.
