ASFAddr.
ASF Assigned Address Register
RO
Before activating ASF, user must go through the ARP (Address Resolution Protocol) to dynamically
get a valid address to manipulate ASF commands. In ARP, a very important ID must be defined to
distinguish different devices, called UDID (Unique Device Identifier). Registers in this section are used
to setup the UDID content.
For detailed operation of ARP and UDID, you can refer to SMBus Specification version 2.0
(http://www.smbus.org/specs/smbus20.pdf ) section 5.6 page 34.
8.13.1.2 ASF Sensor Entity Definition Registers
In ASF Sensor, each sensor channel has 2 parameters to tell ASF host its related location information
on the platform. They are entity Instance and entity ID. In case of user uses the temperature sensor in
locations different with default specified, W83793G provides all channel parameter programmable to
fit customers’ application.
