SensorPath Device Setting and Scanning

SensorPath Devices Setting

For HM support, one LM96011 device, one LM96010 device or one LM96012 device must be connected to the SensorPath

bus. If the LM96011 device is connected, an LM95010 device can also be connected (this is optional).

The following settings are performed, depending on the result of the Extended Device Enumeration (see “Extended Device

Enumeration” on page 131).

SensorPath Device Scanning

The HM automatically reads the data from the sensors.

After the HM completes device enumeration and setting, it is ready to accept an attention request from an LMxx Sensor

device. When an attention request is received, the HM scans all the available LMxx Sensor devices to detect the source of

the attention request.

LM96011: ● Function 1 is enabled by setting to 1 EnF1 bit in the Device Control Register (location 0101b).

● Function 2 is enabled by setting to 1 EnF2 bit in the Device Control Register (location 0101b).

● Attention request for function number 1 sensors is enabled by setting ATE bit in Temperature Control reg-

ister to 1 (location 1010b).

● Temperature sensors SN0 and SN1 are enabled by setting EnS0 and EnS1 in Temperature Control reg-

ister to 1 (location 1010b).

● Attention request for function number 2 sensors is enabled by setting ATE bit in Voltage Control register

to 1 (location 10010b).

● Voltage sensors SN0, SN1, SN2, SN3 and SN4 are enabled by setting EN0, EN1, EN2, EN3 and EN4 in

Voltage Control register to 1 (location 10010b).
