INTERNAL BLOCK FUNCTIONS
3.1
MEMORY SPACE
A memory space of 1 Mbytes can be accessed. Fig. 3-1 shows that memory space. The program memory mapping
differs depending on the EA pin status.
(1)
μ
PD78217A (EA = L)
The program memory is mapped onto external memory (64256 bytes: 00000H to 0FAFFH). This area can also
be used as data memory.
The data memory is mapped onto internal RAM (1024 bytes: 0FB00H to 0FEFFH). In the 1-Mbyte expansion
mode, external memory (960 Kbytes: 10000H to FFFFFH) is mapped as expanded data memory.
(2)
μ
PD78218A (EA = H)
The program memory is mapped onto internal ROM (32 Kbytes: 00000H to 07FFFH) and external memory (31488
bytes: 08000H to 0FAFFH). The external memory is accessed in the external memory expansion mode. The area
mapped onto the external memory can also be used as data memory.
The data memory is mapped onto internal RAM (1024 bytes: 0FB00H to 0FEFFH). In the 1-Mbyte expansion
mode, external memory (960 Kbytes: 10000H to FFFFFH) is mapped as expanded data memory.
