6. CPU ARCHITECTURE
6.1 Memory Space
A memory space of 1 MByte can be accessed. Mapping of the internal data area (special function registers and
internal RAM) can be specified the LOCATION instruction. The LOCATION instruction must be always executed
after RESET cancellation, and must not be used more than once.
(1) When LOCATION 0 instruction is executed
Internal memory
The internal data area and internal ROM area are mapped as follows:
Part Number
Internal Data Area
Internal ROM Area
m
PD784214Y
0F100H-0FFFFH
00000H-0F0FFH
10000H-17FFFH
m
PD784215Y
0EB00H-0FFFFH
00000H-0EAFFH
10000H-1FFFFH

0DF00H-0FFFFH
00000H-0DEFFH
10000H-1FFFFH
Caution
The following areas that overlap the internal data area of the internal ROM cannot be used when
the LOCATION 0 instruction is executed.
