Bit POR; notes 1 and 2
Notes
1.
At power-on or during a power voltage dip, an internal power-on reset signal is generated which resets the I
2
C-bus
data bits to a predefined state. When the internal data bits are found to be in POR state (due to an actual power-on
reset but also if set via the I
2
C-bus) bit POR signals logic 1.
Using the POR bit to detect the occurrence of a power-on reset requires bit PORR to be set logic 1 after power-up.
Setting bit PORR forces the POR bit to logic 0 independent of other I
2
C-bus bit settings. After calibration is completed
also the CALR bit can be used to detect a power-on reset; calibration will be lost in such situation which is signalled
by CALR = 0.
2.
LIMITING VALUES
In accordance with the Absolute Maximum Rating System (IEC 134).
