Bit | Field | Type | Reset | Description |
---|---|---|---|---|
7-5, 0 | REF STATUS CHB, REF STATUS CHD, REF STATUS CHA, REF STATUS CHC | Read Only | 0h | When internal reference diagnostic is enabled by setting EN REF STATUS CHECK bit to ‘1’, these bits carry status of internal reference for corresponding channel.
See Internal Reference and Clock Status Check for details. Note that these bits are multiplexed with temperature sensor’s data and carry TEMPDATA[3:0] if temperature sensor’s is enabled. |
4 | CLK STATUS | Read Only | 0h | This bit indicates presence of input clock. By default, device sets this bit 0. If input clock is absent, this bit becomes '1' |
7-5, 3-1, 0 | TEMPDATA [6:0] | Read Only | 0h | When temperature sensor’s data is being read, these bits carry seven MSBs of temperature sensor’s 9-bit data. Remaining two LSBs are available on address 11h bit 5:4.
See Temperature Sensor for details of operation. |
