8.2
Access Interfaces
2
The W83627DHG-P provides two interfaces, LPC and I
C, for the microprocessor to read or write the
internal registers of the hardware monitor.
8.2.1
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.
