Memory Maps
By default, the chip reset address and COP reset address correspond to vector 0 and 1 of the interrupt vector table. In these
instances, the first two locations in the vector table must contain branch or JMP instructions. All other entries must contain JSR
instructions.
Table 48 on page 85
4.5
The locations of on-chip peripheral registers are part of the data memory map on the 56800E series. These locations may be
accessed with the same addressing modes used for ordinary data memory. However, all peripheral registers should be read or
written using word accesses only.
Table 12
listed in order of the base address.

The 56F824x’s startup address is located at 0x00 2000. The reset value of VBA is reset to a value of 0x0020 that
corresponds to the address 0x00 2000.
