Table 5-31. F0BAR1+I/O Offset: LPC Interface Configuration Registers (Continued)
Description
IRQ12 Polarity. If LPC is selected as the interface source for IRQ12 (F0BAR1+I/O Offset 00h[12] = 1), this bit allows signal
polarity selection.
0: Active high.
1: Active low.
IRQ11 Polarity. If LPC is selected as the interface source for IRQ11 (F0BAR1+I/O Offset 00h[11] = 1), this bit allows signal
polarity selection.
0: Active high.
1: Active low.
IRQ10 Polarity. If LPC is selected as the interface source for IRQ10 (F0BAR1+I/O Offset 00h[10] = 1), this bit allows signal
polarity selection.
0: Active high.
1: Active low.
IRQ9 Polarity. If LPC is selected as the interface source for IRQ9 (F0BAR1+I/O Offset 00h[9] = 1), this bit allows signal
polarity selection.
0: Active high.
1: Active low.
IRQ8# Polarity. If LPC is selected as the interface source for IRQ8# (F0BAR1+I/O Offset 00h[8] = 1), this bit allows signal
polarity selection.
0: Active high.
1: Active low.
IRQ7 Polarity. If LPC is selected as the interface source for IRQ7 (F0BAR1+I/O Offset 00h[7] = 1), this bit allows signal
polarity selection.
0: Active high.
1: Active low.
IRQ6 Polarity. If LPC is selected as the interface source for IRQ6 (F0BAR1+I/O Offset 00h[6] = 1), this bit allows signal
polarity selection.
0: Active high.
1: Active low.
IRQ5 Polarity. If LPC is selected as the interface source for IRQ5 (F0BAR1+I/O Offset 00h[5] = 1), this bit allows signal
polarity selection.

IRQ3 Polarity. If LPC is selected as the interface source for IRQ3 (F0BAR1+I/O Offset 00h[3] = 1), this bit allows signal
polarity selection.
0: Active high.
1: Active low.
SMI# Polarity. This bit allows signal polarity selection of the SMI# generated from LPC.
0: Active high.
1: Active low.
IRQ1 Polarity. If LPC is selected as the interface source for IRQ1 (F0BAR1+I/O Offset 00h[1] = 1), this bit allows signal
polarity selection.
0: Active high.
1: Active low.
IRQ0 Polarity. If LPC is selected as the interface source for IRQ0 (F0BAR1+I/O Offset 00h[0] = 1), this bit allows signal
polarity selection.
