Architecturally, the LPC serves as a PCI-to-ISA bridge to devices connected to the LPC 

interface pins. The bridge is discovered by the software at bus 0, device 31 (decimal), 

function 0 in the configuration address space. This bridge also accommodates a 

number of integrated legacy peripherals, most of which were originally designed for the 

Industry Standard Architecture (ISA). These legacy peripherals are integrated in the 

SoC:

•

 interface with 31 interrupts synchronized 

with the LPC clock

•

 registers and interface pins

•

•

 with PC speaker capability

•

•

•

These legacy devices are described in other chapters. The PCI-to-ISA bridge and the 

LPC interface to external devices are described in this chapter.
