Preliminary
1. Two words are allocated for each entry in the vector table. This does not allow the full address range to be referenced from the
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 the chip

1. All addresses are 16-bit Word addresses, not byte addresses.
2. In the Operating Mode Register (OMR).
3. The Data RAM is organized as a 2K x 32-bit memory to allow single-cycle long-word operations.
