Preliminary
Table 4-4 shows the memory map options of the 56F8335/56F8135. The two right columns cannot be
used, since the EMI pins are not provided in the package; therefore, only the Mode 0 column is relevant.
Note: Program RAM is NOT available on the 56F8135 device.
1. Cannot be used since MA = EXTBOOT = 0 and the EMI is not available; information in shaded areas not applicable to
56F8335/56F8135.
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 VDD 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
56F8335/56F8135.
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
1. Setting this bit can cause unpredictable results and is not recommended, since the EMI is not functional in this package.
