*1: LR 00000 to LR 00199 are converted to CIO 01000 to CIO 01199.
*2: The EM Area is supported only by the C200HX/HG/HE(-Z)E PCs.
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 Map on page 435.
The relationships among the allocated words, the number of allocated words,
and the contents of numeral memory table entry are indicated in the figure be-
low.

Storage Type and Stored Data
A numeral memory table entry internally stores the specified number of words of
data as signed binary data. When the contents of words allocated in the host are
stored in a memory table entry, the numeric value is interpreted according to the
Storage Type setting and is stored after conversion to signed binary data. Also,
the signed binary data in numeral memory table entries is written to the words
allocated in the host according to the Storage Type setting.
Accordingly, different Storage Type settings will cause the same data to be rec-
ognized by the PT as different values and written to the host as different values.
Reference: Signed binary data expresses negative values as the complement of two (the bits
are inverted and 1 is added).
