IN1, TXF, Transmit Fault (TXFOUT) Output
TXFOUT can be triggered by all alarms and warnings and
also the pins TXF and IN1 (Figure 10). The ADC alarms and
warnings require enabling (A2h Table 01h/05h, Registers
F8h and FDh). See Figure 12a and Figure 12b for non-
latched and latched operation. Figure 12c describes
this TXFOUT behavior during power-on. Latching of the
alarms is controlled by CNFGB and CNFGC Registers
Die Identification
The DS1884 has an ID hardcoded in its die. Two reg-
isters (DEVICE ID A2h Table 02h, Register CEh and
DEVICE VER A2h Table 02h, Register CFh) are assigned
for this feature. Register CEh reads 84h to identify with
the device as the DS1884, and Register CFh reads the
present device version.
