Hitachi H8/300
--------------

`target hms DEV'
     A Hitachi SH, H8/300, or H8/500 board, attached via serial line to
     your host.  Use special commands `device' and `speed' to control
     the serial line and the communications speed used.

`target e7000 DEV'
     E7000 emulator for Hitachi H8 and SH.

`target sh3 DEV'
`target sh3e DEV'
     Hitachi SH-3 and SH-3E target systems.

   When you select remote debugging to a Hitachi SH, H8/300, or H8/500
board, the `load' command downloads your program to the Hitachi board
and also opens it as the current executable target for GDB on your host
(like the `file' command).

   GDB needs to know these things to talk to your Hitachi SH, H8/300,
or H8/500:

  1. that you want to use `target hms', the remote debugging interface
     for Hitachi microprocessors, or `target e7000', the in-circuit
     emulator for the Hitachi SH and the Hitachi 300H.  (`target hms' is
     the default when GDB is configured specifically for the Hitachi SH,
     H8/300, or H8/500.)

  2. what serial device connects your host to your Hitachi board (the
     first serial device available on your host is the default).

  3. what speed to use over the serial device.
