11.12 Instance Description
There are two blocks defined in this chapter: Emulated 8042 Interface and the Legacy Port92/GATEA20 Support. The
MEC1322 has one instance of each block.
11.13 Configuration Registers
The registers listed in the Configuration Register Summary table are for a single instance of the Emulated 8042 Inter-
face. The addresses of each register listed in this table are defined as a relative offset to the host “Base Address” defined
in the Configuration Register Base Address Table.
Each Configuration register access through the Host Access Port is via its LDN and its Host Access Port Index. EC
access is a relative offset to the EC Base Address.
