Bit(s) Bit Name Read/ Description
Write
7–0 - WO Writing to this register activates one conversion for all the enabled channels if
the chip is in standby mode (i.e. standby bit = 1). The actual data written does
not matter and is not stored.

Bit(s) Bit Name Read/ Description
Write
7 BUSY RO Busy bit (device converting)
6 NR RO Not Ready bit (30 ms), indicates power up initialization sequence is in progress
5–4 – RO Reserved – will report "0" when read.
3 SR4F RO Status Register 4 Flag:
1 – indicates that Status Register 4 has at least one bit set
0 – indicates that all of Status Register 4 bits are cleared
2 SR3F RO Status Register 3 Flag:
1 – indicates that Status Register 3 has at least one bit set
0 – indicates that all of Status Register 3 bits are cleared
1 SR2F RO Status Register 2 Flag:
1 – indicates that Status Register 2 has at least one bit set
0 – indicates that all of Status Register 2 bits are cleared
0 SR1F RO Status Register 1 Flag:
1 – indicates that Status Register 1 has at least one bit set
0 – indicates that all of Status Register 1 bits are cleared
Status 1 Register (Diode Fault)
Status fault bits for open or shorted diode (i.e. Short Fault: D+ shorted to Ground or D-; Open Fault: D+ shorted
to V
DD
, or floating). During fault conditions the temperature reading is 0 °C if unsigned value registers are read or
–128.000 °C if signed value registers are read.
