4.3 Interrupt Vector Table
Table 4-5
organized with higher-priority vectors at the top and lower-priority interrupts lower in the table. The
priority of an interrupt can be assigned to different levels, as indicated, allowing some control over
interrupt priorities. All level 3 interrupts will be serviced before level 2, and so on. For a selected priority
level, the lowest vector number has the highest priority.

1. If Flash Security Mode is enabled, EXTBOOT Mode 1 cannot be used. See Security Features,
2. This mode provides maximum compatibility with 56F80x parts while operating externally.
3. “EMI_MODE = 0” when EMI_MODE pin is tied to ground at boot up.
4. “EMI_MODE = 1” when EMI_MODE pin is tied to V
5. Not accessible in reset configuration, since the address is above P:$00 FFFF. The higher bit address/GPIO (and/or chip
6. Not accessible in reset configuration, since the address is above P:$0F FFFF. The higher bit address/GPIO (and/or chip
7. Booting from this external address allows prototyping of the internal Boot Flash.
