2.0 Register Set
2.6 CAPABILITIES FIXED (Addr 03o)
The value of this register defines the capabilities of the LM95010. The LM95010 supports only one function, that of Temperature
Measurement type. Please refer to the SensorPath specification for further details on other FuncDescriptor values.
2.7 DEVICE STATUS (Addr 04o)
This register is set to the reset value by a Device Reset.
Reg Add
2.8 DEVICE CONTROL (Addr 05o)
This register responds to a broadcast write command (DeviceNumber 000). Write using broadcast address is ignored by bits
15-2. This register is set to the reset value by a Device Reset.

SF1 (Status Function 1). This bit is set by a Function Event within Function 1. Event details are function
dependent and are described within the function. SF1 is cleared by Device Reset or by handling the event
within the function (see Section 2.9 for further details).
0: Status flag for Function 1 is inactive (no event).
1: Status flag for Function 1 is active indicating that a Function Event has occurred.
Not supported. Will always read "0".
ERF1 (Error Function 1) This bit is set in response to an error indication within Function 1. ERF1 is cleared
by Device Reset or by handling the error condition within the function (see Section 2.9 for further details).
0: No error occurred in Function 1.
1: Error occurred in Function 1.
Not supported. Will always read "0".
BER (Bus Error). This bit is set when the device either generates, or receives an error indication in the ACK
bit of the transaction (i.e., no-acknowledge). BER is cleared by Device Reset or by reading the Device Status
register.
0: No transaction error occurred.
1: An ACK bit error (no-acknowledge) occurred during the last transaction.
self-clears after the Device Reset operation is completed.
0: Normal device operation. (default)
1: Device Reset
The LM95010 does not require a Device Reset command after power.
