Busy
When set to "1" the part is converting.

Remote 2 TruTherm Mode Enabled
When set to "1" indicates that the TruTherm Mode has been activated for
(R2TME)
Remote diode 2. After being enabled TruTherm Mode will take at most one
conversion cycle to be fully active.
2
Remote 1 TruTherm Mode Enabled
When set to "1" indicates that the TruTherm Mode has been activated for
(R2TME)
Remote diode 1. After being enabled TruTherm Mode will take at most one
conversion cycle to be fully active.
1
Remote Diode 2 Missing (RD2M)
When set to "1" Remote Diode 2 is missing. (i.e. D2+ shorted to VDD, Ground
or D2-, or D2+ is floating). Temperature Reading is FFE0h which converts to
255.875 °C if unsigned format is selected or 8000h which converts to
–128.000 °C if signed format is selected. Note, connecting a 2N3904 transistor
to Remote 2 inputs with TruTherm mode active may also cause this bit to be
set.
0
Remote Diode 1 Missing (RD1M)
When set to "1" Remote Diode 1 is missing. (i.e. D1+ shorted to VDD, Ground
or D1-, or D1+ is floating). Temperature Reading is FFE0h which converts to
255.875 °C if unsigned format is selected or 8000h which converts to
–128.000 °C if signed format is selected. Note, connecting a 2N3904 transistor
to Remote 1 inputs with TruTherm mode active may also cause this bit to be
set.

RUN/STOP
Logic 1 disables the conversion and puts the part in standby mode.
Conversion can be activated by writing to one-shot register.
5-4
Conversion Rate (CR1:CR0)
00: continuous mode 75.8 ms, 13.2 Hz (typ), when diode mode is selected for
both remote channels; 77.5 ms, 12.9 Hz (typ), when TruTherm Mode is
enabled for one remote channel.
01: converts every 182 ms, 5.5 Hz (typ)
10: converts every 1 second, 1 Hz (typ)
11: converts every 2.7 seconds, 0.37 Hz (typ)
Note: typically a remote diode conversion takes 30 ms with diode mode is
selected; when the TruTherm Mode is selected a conversion takes an
additional 1.7 ms; a local conversion takes 15.8 ms.

Remote 1 Data Format (R1DF)
Logic 0: unsigned Temperature format (0 °C to +255.875 °C)
Logic 1: signed Temperature format (-128 °C to +127.875 °C)
