1. Two words are allocated for each entry in the vector table. This does not allow the full address range to be referenced
2. If the VBA is set to $0400 (or VBA = 0000 for Mode 1, EMI_MODE = 0), the first two locations of the vector table are
1. Information in shaded areas not applicable to 56F8365/56F8165.
2. All addresses are 16-bit Word addresses, not byte addresses.
3. In the Operating Mode Register
4. Setting EX = 1 is not recommended in the 56F8365/56F8165, since the EMI is not functional in this package.
5. The Data RAM is organized as an 8K x 32-bit memory to allow single-cycle, long-word operations.
