2.4 STATUS REGISTERS
2.4.1 Common Status Register
2.4.2 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
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.

Description
Busy bit (device converting)
Not Ready bit (30 ms), indicates power up initialization sequence is in progress
Reserved – will report "0" when read.
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
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
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
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

Description
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.
