Access Interface
W83627EHF/EHG provides two interface for microprocessor to read/write hardware monitor internal
registers.
7.2.1
LPC interface
The first interface uses LPC Bus to access which the ports of low byte (bit2~bit0) are defined in the port
5h and 6h. The other higher bits of these ports are set by W83627EHF/EHG itself. The general
decoded address is set to port 295h and port 296h. These two ports are described as following:
Port 295h: Index port.
Port 296h: Data port.
The register structure is showed as the Figure 7.1
