4.4.3 List of variables for Analyzer function

Table 4-1 is a list of variables for Analyzer. These variables are reflected to the corresponding variables
when the same values as g_u1_enable_write are written to com_u1_enable_write. However, note that
variables with (*) do not depend on com_u1_enable_write.
