Table B−1. Checksum Computation Memory Locations
Address
0x3D7800 1K OTP for customer code. (referred to in this document as Customer-OTP)
....
0x3D7BFB
0x3D7BFC † Low-word of D-number
0x3D7BFD † High-word of D-number
0x3D7BFE † Low-word of checksum (for Customer-OTP)
0x3D7BFF † High-word of checksum (for Customer-OTP)
0x3D7C00 1K OTP for TI test code. (referred to in this document as TI-OTP)
....
0x3D7FFD
0x3D7FFE Low-word of checksum (for TI-OTP)
0x3D7FFF High-word of checksum (for TI-OTP)
0x3D8000 ‡ Start address for customer code in ROM (referred to in this document as Customer-
.... ROM)
0x3F7FF1 End address for customer code in ROM
0x3F7FF2 † Low-word of D-number
0x3F7FF3 † High-word of D-number
0x3F7FF4 † Low-word of checksum (for Customer-ROM)
"Customer-OTP" area, including the D-number. Addresses
-
0x3D7BFE and 0x3D7BFF, which are eventually used to store
the checksum are not used in the computation.
TI-OTP area containing TI test code. Addresses 0x3D7FFE and
-
0x3D7FFF, which are eventually used to store the checksum are
not used in the computation.
"Customer ROM" area, including the ROM entry-point and CSM
-
passwords. Addresses 0x3F7FF4 and 0x3F7FF5, which are
eventually used to store the checksum are not used in the com-
putation.
The computed checksum is written into the corresponding locations
(see Table B−1). The image of the ROM is now ready in the PC
memory.
