*1: Words LR 00000 to LR 00199 are converted to CIO 01000 to CIO 01199.
*2: The EM Area is valid for the C200HX/HG/HE(-Z)E PCs only.
The Auxiliary Area of the CVM1 and CV-series PCs is allocated to system func-
tions, and it cannot be used for purposes other than system use.
The range of each memory area differs according to the PC. Refer to
Appendix D
PC Memory Maps on page 429.
The relationships among the allocated words, the number of allocated words,
and the contents of character string memory tables are indicated in the figure
below.

Resume Function and Initial Values
When the resume function is not used, the preset initial values are written in the
character string memory tables when the power to the PT is turned ON, the PT is
reset, or the PT is switched to RUN mode from the System Menu. (See Initialize
below.)
Use the resume function to prevent initialization and retain the last values that
were in place before operation stopped.
Resume setting Character string memory table contents
Yes The previous character string memory table values are used.
No The character string memory table’s initial values are used.
The System Menu’s initialize operation can be used to write the initial values to
the memory tables regardless of the resume function setting. When the resume
function is used, the previous values will be used even if the initial values are
changed, so changes to the initial values won’t be reflected in the tables. Initial-
ize the memory table values before starting operation to reflect changes in initial
values.
