Preliminary
1. Information in shaded areas not applicable to 56F8335/56F8135.
2. All addresses are 16-bit Word addresses, not byte addresses.
3. In the Operation Mode Register.
4. Setting EX = 1 is not recommended in the 56F8335/56F8135, since the EMI is not functional in this package.
5. The Data RAM is organized as a 2K x 32-bit memory to allow single-cycle, long-word operations.

Begin/End Address
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 $0200 (or VBA = 0000 for Mode 1, EMI_MODE = 0), the first two locations of the vector table are

from the vector table, providing only 19 bits of address.
the chip reset addresses; therefore, these locations are not interrupt vectors.
