Memory Configuration Modes
Use the Memory Configuration dialog box to select the memory configuration mode:
auto configuration on access, auto configuration on load, or manual configuration
(user defined). Depending on your settings, the FCS component initializes the FCS
memory as Table 28.2 explains.
Memory Configuration Settings
Depending on the configuration mode, the Memory Configuration dialog box lets you
redefine memory settings within certain limits. You must always set I/O devices manually.
Standard Configuration: Auto on Access: The Memory Configuration dialog box contains
a single RAM entry with unspecified (*) starting and ending addresses. You cannot
modify these addresses. You can adjust wait states, and other such settings, only for the
whole RAM block.
Auto Configuration on Load: Initially, the dialog box lists a single RAM and a single
ROM block, with unspecified (*) starting and ending addresses. You can adjust wait states
and other settings separately for RAM and ROM blocks.
For the ELF/DWARF Object file format, the Memory Configuration dialog box lists
separate RAM and ROM blocks for each data and code segment in the absolute file, once
an application has been loaded. The segment addresses and lengths determine the starting
and ending addresses of each block; you cannot modify these addresses. Initial attributes
of each code and data block come from the corresponding initial RAM and ROM blocks;
you can modify these attributes independently.

Mode Description
Auto Configuration on Access
(Standard Configuration)
Defines the FCS memory as RAM of unlimited size.
The
Mode
combo box displays
auto on access
.
Auto Configuration on Load
(default)
Defines the FCS memory as RAM and ROM,
according to the code and data area defined in a
loaded absolute file. Defines code segments as ROM.
Defines data segments as RAM. (Memory outside
these segments is
not implemented
; access to
unimplemented locations result in error messages.)
The
Mode
combo box displays
auto on load
.
Manual Configuration (User
Defined)
Defines the FCS memory as RAM, ROM, or non-
volatile RAM, depending on your configuration. You
construct this definition interactively with the Memory
Configuration dialog box, or read it in from a file. The
Mode
combo box displays
user defined
.
