NOTE

Reserved register space shown in Table 1-2 is not allocated to any module.

This register space is reserved for future use. Writing to these locations has

no effect. Read access to these locations returns zero.

Figure 1-2, Figure 1-3 and Figure 1-4 shows S12HY/HA family CPU and BDM local address translation

to the global memory map. It indicates also the location of the internal resources in the memory map.

Table 1-3 shows the mapping of D-Flash and unpaged P-Flash memory. The whole 256K global memory

space is visible through the P-Flash window located in the 64K local memory map located at 0x8000

−

0xBFFF using the PPAGE register.
