In either case, @value{GDBN} sees the effect of a @sc{reset} on the
development board as a ``normal exit'' of your program.
@node Hitachi ICE
@subsubsection Using the E7000 in-circuit emulator
@kindex target e7000
You can use the E7000 in-circuit emulator to develop code for either the
Hitachi SH or the H8/300H. Use one of these forms of the @samp{target
e7000} command to connect @value{GDBN} to your E7000:
@table @code
@item target e7000 @var{port} @var{speed}
Use this form if your E7000 is connected to a serial port. The
@var{port} argument identifies what serial port to use (for example,
@samp{com2}). The third argument is the line speed in bits per second
(for example, @samp{9600}).
@item target e7000 @var{hostname}
If your E7000 is installed as a host on a TCP/IP network, you can just
specify its hostname; @value{GDBN} uses @code{telnet} to connect.

@node Hitachi Special
@subsubsection Special @value{GDBN} commands for Hitachi micros
Some @value{GDBN} commands are available only on the H8/300 or the
H8/500 configurations:
@table @code
@kindex set machine
@kindex show machine
@item set machine h8300
@itemx set machine h8300h
Condition @value{GDBN} for one of the two variants of the H8/300
architecture with @samp{set machine}. You can use @samp{show machine}
to check which variant is currently in effect.
@kindex set memory @var{mod}
@cindex memory models, H8/500
@item set memory @var{mod}
@itemx show memory
Specify which H8/500 memory model (@var{mod}) you are using with
@samp{set memory}; check which memory model is in effect with @samp{show
memory}. The accepted values for @var{mod} are @code{small},
@code{big}, @code{medium}, and @code{compact}.
