Preliminary
Table 4-4 shows the memory map options of the device. 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 56F8155 device.
1. Cannot be used since MA = EXTBOOT = 0 and the EMI is not available; information in shaded areas not applicable to
56F8355/56F8155.
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.

1. Setting this bit can cause unpredictable results and is not recommended, since the EMI is not functional in this package.
Use external P-space memory map configuration – If MB = 0 at reset, changing this bit has no
effect.
