Base Address Register 1 (BAR1)—Offset 14h
Memory accesses to BAR1 region access the PCI configuration space for the LPIO
device. BAR1 region is always 4K. However SW accesses through BAR1 should only
access the regular PCI configuration space. BAR1 memory accesses which do not
access a defined PCI configuration register are treated as accesses to a reserved
register.
Access Method
Default: 00000000h
