2.2 External Signal Description
The Flash module contains no signals that connect off-chip.
2.3 Memory Map and Register Definition
This subsection describes the memory map and registers for the Flash module.
2.3.1 Module Memory Map
The Flash memory map is shown in Figure 2-2. The HCS12 architecture places the Flash memory
addresses between 0x4000 and 0xFFFF which corresponds to three 16-Kbyte pages. The content of the
