7.2 Customer Information Fields in the ROM
Customer code information is inserted in the ROM by Texas Instruments. This
information appears as seven distinct fields within the ROM test-area. The
ROM test-area extends from address 0x0000 to 0x07FF. The code-release
information is stored in locations 0x0006 through 0x000C. Assuming these
addresses are not specifically read-protected by the ROM security, they are
read-accessible to the programmer. The fields appear as follows:
MSP50C614 EPROM Test-Area

th bit is ignored)
