19.2 External Signal Description
The FTS128K1FTS64K module contains no signals that connect off-chip.
19.3 Memory Map and Registers
This section describes the FTS128K1FTS64K memory map and registers.
19.3.1 Module Memory Map
The FTS128K1FTS64K memory map is shown in Figure 19-3Figure 19-4. The HCS12 architecture places
the Flash array addresses between 0x40000x4000 and 0xFFFF, which corresponds to three 16 Kbyte
pages. The content of the HCS12 Core PPAGE register is used to map the logical middle page ranging from
