Separate Space Modes
Code memory space is separated from data mem-
ory space. For example, the PSEN signal is used
to access the program code from the Flash Mem-
ory, while the RD signal is used to access data
from the EEPROM, SRAM and I/O Ports. This
configuration requires the VM register to be set to
0Ch. See
Figure 12.
Combined Space Modes
The program and data memory spaces are com-
bined into one space that allows the main Flash
Memory, EEPROM, and SRAM to be accessed by
either PSEN or RD. For example, to configure the
main Flash memory in combined space mode, bits
2 and 4 of the VM register are set to
1
(see Figure
13
).
