PWRBTN or Power button :If the soft power management is enabled, a low signal in this pin turns the
system on or off.
Notes:
The +5VSB (Volt Stand-By) voltage is useful for Power management applications only.
The +12VDC and -5VDC voltages are neither used nor generated by the CPU-1450
module: they are only conveyed on the PC/104-Plus bus (connector J1) and can be
used by other devices or modules that are stacked onto the CPU module.
Warning:
Improper connection of the power supply will result in serious damage to the module.
