1.7 M3A-HS19 Memory Mapping Area 0 bus width: (Default) MD3 = 0 •••16-bit
Data alignment: (SW4-1) MD5 = 0(ON) •••Big endian
MD5 = 1(OFF) •••Little endian
Figure 1.7.1 show the memory mapping examples of the SH7619 on the M3A-HS19.
Logical Address [31~29] Area Cacheable/Non-cacheable
000~011 P0 Cacheable
100~ P1 Cacheable
101~ P2 Non cacheable
110~ P3 Cacheable
111~ P4 Non-cacheable (on-chip I/O) etc.
