†
These addresses are reserved for the ROM code generation flow and cannot be used by customer code. Using these locations
to store the D-number and checksum does not compromise code security.
‡
The start address for customer code in ROM depends on the part number. While the start address is 0x3D8000 for
C2812/C2811, it is 0x3E8000 for C2810. The customer code should provide a branch instruction and the corresponding address
at locations 0x3F7FF6 & 0x3F7FF7.
Step 4:
Saving the COFF files for gate placement
The ROM image is saved into two COFF files, one for the OTP and
the other for the main ROM array. The files are named as follows:
DExxy000_OTP.out – ROM image for the OTP
DExxy000_main.out – ROM image for the main ROM array.
These two files will be sent to the customer for approval.
