+@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.

+@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}.
