6.3.1.1 LPC Decoding
The LPC bus supports different protocols.
6.3.1.1.1 LPC I/O Decoding
The LPC interface responds to LPC I/O accesses listed in Table 6-6 LPC I/O Register Map
Overview. All other LPC I/O accesses are ignored.
All LPC I/O accesses to address POSTCODE, within the address range REGISTERS and within the
address ranges of COM1 or COM2 (only when enabled during Super IO configuration) are
decoded by the LPC core.
6.3.1.1.2 LPC Memory Decoding
The LPC interface never responds to LPC Memory accesses.
6.3.1.1.3 LPC Firmware Decoding
The LPC interface never responds to LPC Firmware accesses.
