Separate Space Mode.
Program space is sepa-
rated fromData space. For example, Program Se-
lect Enable (PSEN) is used to access the program
code from the primary Flash memory, while READ
Strobe (RD) is used to access data from the sec-
ondary Flash memory, SRAM and I/O Port blocks.
This configuration requires the VM Register to be
set to 0Ch (see Figure 55).
Combined Space Modes.
The
Data spaces are combined into one memory
space that allows the primary Flash memory, sec-
ondary Flash memory, and SRAM to be accessed
by either Program Select Enable (PSEN) orREAD
Strobe (RD). For example, to configure the prima-
ry Flash memory in Combined space, Bits b2 and
b4 of the VMRegister are set to ’1’(see Figure56).
