56F8345 Technical Data
Preliminary
1. Cannot be used since MA = EXTBOOT = 0 and the EMI is not available; information in shaded areas not applicable to
56F8345.
2. This mode provides maximum compatibility with 56F80x parts while operating externally.
3.
“EMI_MODE = 0”, EMI_MODE pin is tied to ground at boot up.
4. “EMI_MODE = 1”, EMI_MODE pin is tied to V
DD
at boot up.
5. Not accessible in this part, since the EMI is not fully pinned out in this package; information in shaded areas not applicable
to 56F8345.
4.3 Interrupt Vector Table
Table 4-5
provides the reset and interrupt priority structure, including on-chip peripherals. The
table is 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.
The location of the vector table is determined by the Vector Base Address (VBA) register. Please
see
Section 5.6.11 Vector Base Address Register (VBA)
for the reset value of the VBA.
In some configurations, the reset address and COP reset address will correspond to vector 0 and 1
of the interrupt vector table. In these instances, the first two locations in the vector table must
contain branch or JMP instructions. All other entries must contain JSR
instructions.
