GTM debugging function
Specifications for debugging the GTM are listed in the table below. The table only shows functions for the
GTM. The functions for the CPU shown in Table 4-1, except for downloading, can be used at the same time
as those for the GTM. Support for some debugging-related functions also depends on the debugger. Refer to
the user’s manual, etc. for the debugger you are using.
