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
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 this part, since the EMI is not fully pinned out in this package; information in shaded areas not applicable to
