Remote 2 TruTherm Mode
Enabled (R2TME)
Description
When set to "1" the part is converting.
Reports "0" when read.
When set to "1" indicates that the TruTherm Mode has been activated
for Remote diode 2. After being enabled TruTherm Mode will take at
most one conversion cycle to be fully active. This bit will be set even if
the diode is desconnected.
When set to "1" indicates that the TruTherm Mode has been activated
for Remote diode 1. After being enabled TruTherm Mode will take at
most one conversion cycle to be fully active. This bit will be set even if
the diode is disconnected.
When set to "1" Remote Diode 2 is missing. (See Section 1.6 for
further details.) 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 3904
transistor to Remote 2 inputs with TruTherm mode active may also
cause this bit to be set.
When set to "1" Remote Diode 1 is missing. (See Section 1.6 for

Description
Reports "0" when read.
Logic 1 disables the conversion and puts the part in standby mode.
Conversion can be activated by writing to one-shot register.
00: continuous mode 76.5 ms, 13.1 Hz (typ), when TruTherm Mode is
disabled (Diode Equation) for both remote channels; 77.8 ms, 12.9 Hz
(typ), when TruTherm Mode is enabled (Transistor Equation) 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)
Reports "0" when read.
Logic 0: unsigned Temperature format (0 C to +255.875 C)
Logic 1: signed Temperature format (-128 C to +127.875 C)
Logic 0: unsigned Temperature format (0 C to +255.875 C)
Logic 1: signed Temperature format (-128 C to +127.875 C)
Reports "0" when read.
