27 / 44 page  LM95233 www.ti.com SNIS145E – AUGUST 2006 – REVISED MARCH 2013 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. STATUS REGISTERS Common Status Register Register Name Command Read/ D7 D6 D5 D4 D3 D2 D1 D0 POR Byte Write Default (Hex) (Hex) Common Status Register 0x02 RO BUSY NR – – SR4F SR3F SR2F SR1F 0x00 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 VDD, 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.
