• Manufacturer Part Number: MC56F836
• Description: 56f8300 16-bit Digital Signal Controllers
• Manufacturer: Freescale Semiconductor, Inc

1. Cannot be used since MA = EXTBOOT = 0 and the EMI is not available; information in shaded areas not applicable to
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
5. Not accessible in reset configuration, since the address is above P:$00 FFFF. The higher bit address/GPIO (and/or chip selects)
6. Not accessible in this part, since the EMI is not fully pinned out in this package; information in shaded areas not applicable
7. Two independent program flash blocks allow one to be programmed/erased while executing from another. Each block must have

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
