6.4. 7-SEGMENT LED DISPLAY DATA OUTPUT PORT (3F-F040H [Write Only])
This port sets the data to be displayed on the 7-segment LED on the Base board. The data format is
as shown in table below. Setting a bit to 0 causes the corresponding segment to light.

6.5. DIPSW1 READ PORT (3F-F050H [READ ONLY])
This port is used to read the status of DIPSW1 on the Base board. The data format is as shown in
table below.

SW1-[8..1]: The status of SW1 on the Base board can be read. SW1-1 corresponds to switch
“ 1” of DIP SW1, while SW1-8 corresponds to switch “ 8” of DIP SW1. When a bit is ON, it
represents 0. When a bit is OFF, it represents 1.
Some of the DIPSW1 bits are reserved by the monitor in the ROM mounted on the Base board, as
shown in table below. However, note that these functions are defined in terms of software. This
means that, even when the switch setting is changed, these functions are not affected by this
(hardware-based) action.
