6.4 Interrupt Vector Table and Signatures

The interrupt vectors, the power-up start address and signatures are in the address range 0FFFFh to 0FF80h. Figure 6-1 summarizes the content of this address range.

MSP430FR6979 MSP430FR69791 MSP430FR6977 MSP430FR6928 MSP430FR6927 MSP430FR69271 Interrupts_Signatures_Passwords.gifFigure 6-1 Interrupt Vectors, Signatures, and Passwords

The power-up start address or reset vector is located at 0FFFFh to 0FFFEh. It contains the 16-bit address pointing to the start address of the application program.

The interrupt vectors start at 0FFFDh and extend to lower addresses. Each vector contains the 16-bit address of the appropriate interrupt-handler instruction sequence. Table 6-4 shows the device-specific interrupt vector locations.

The vectors programmed into the address range from 0FFFFh to 0FFE0h are used as the BSL password (if enabled by the corresponding signature).

The signatures are located at 0FF80h and extend to higher addresses. Signatures are evaluated during device start-up. Table 6-5 shows the device-specific signature locations.

A JTAG password can be programmed starting at address 0FF88h and extending to higher addresses. The password can extend into the interrupt vector locations using the interrupt vector addresses as additional bits for the password. The length of the JTAG password depends on the JTAG signature.

See the System Resets, Interrupts, and Operating Modes, System Control Module (SYS) chapter in the MSP430FR58xx, MSP430FR59xx, MSP430FR68xx, MSP430FR69xx Family User's Guide for details.
