CPU Board Switches
Figure 3.1 shows the locations of switches (SW1 to SW5) on the CPU board. In addition, this section gives a
brief description of each switch in (1) to (5).
Figure 3.1 CPU Board Switches (SW1 to WS5)
(1) Power Switch (SW1)
This switch turns on or off the Solution Engine2 unit. To turn on the Solution Engine2 unit, press and hold
down this switch for 0.5 seconds or more. To turn it off, press and hold down this switch for 4 seconds or more
when Solution Engine2 is being powered.
(2) Reset Switch (SW2)
This switch resets Solution Engine2. To reset devices other than the H8/3048-ONE, press this switch. To reset
and restart Solution Engine2, release this switch. In this case, the values of H8/3048-ONE internal registers are
not initialized. Among the control registers, the values of those that can be accessed by SH7760 are initialized
but the others are not (i.e., their values are retained). For more details, refer to 6.13 “ Initial Values of the Power
Supply Controller Register.”
(3) NMI Switch (SW3)
This switch controls the SH7760 NMI pin. Press this switch and the SH7760 NMI pin will go “Low.” Release
this switch, and the NMI pin will go “High.”
