VSB3V Enable GPIO23 IRQ or SMI# Generation. If this bit set to 1, enable
GPIO23 to generate IRQ or SMI#.
VSB3V Enable GPIO22 IRQ or SMI# Generation. If this bit set to 1, enable
GPIO22 to generate IRQ or SMI#.
VSB3V Enable GPIO21 IRQ or SMI# Generation. If this bit set to 1, enable
GPIO21 to generate IRQ or SMI#.
VSB3V Enable GPIO20 IRQ or SMI# Generation. If this bit set to 1, enable
GPIO20 to generate IRQ or SMI#.
