W83627DHG
7.2.1 LPC Interface
This interface uses the LPC bus to access the index and data ports. These two ports are located at the
16-bit port specified in CR60 and CR61, plus 5h and 6h, respectively. If the 16-bit port value is 290h, so
the default index and data port addresses are 295h and 296h, respectively. The structure of the internal
registers is shown in the following figure.
