6.3 Memory Map
The amount and memory locations of the kernel program, to communicate with the KD30 and
ICD, are using on the M16/62P on the SKP16C62P board is shown on Figure 6-2.
Figure 6-2 M30626FHPGP Memory Map with the Kernel Program
Note: The kernel occupies memory associated with special-page vector numbers 18-19 and 192-
255. The user reset vector is re-mapped to address FFFD8h by the kernel.
6.4 Status After Reset
Table 6-2 lists the values of the registers initialized by the kernel program when the SKP16C62P
starter board is reset. The register status depends on the microcomputer’s internal operation
performed after a reset.

6.5 Register Operation Limitations
Table 6-3 lists the limitations on register operation. The registers are inhibited from any
modification. If register contents are modified in any way, kernel operation cannot be guaranteed.
