4.3.4.6
Fault Queue
The fault queue feature can be used as a filter to lessen
the probability of spurious activation of the ALERT pin.
TA must remain above TSET for the consecutive num-
ber of conversion cycles selected using the Fault
Queue bits. Bit 3 and bit 4 of CONFIG can be used to
select up to six fault queue cycles. For example, if six
fault queues are selected, TA must be greater than
TSET for six consecutive conversions before ALERT is
asserted as a comparator or an interrupt output.
This queue setting also applies for THYST. TA must
remain below THYST for six consecutive conversions
before ALERT is deasserted (comparator mode) or
before another interrupt is asserted (interrupt mode).
4.3.4.7
Σ ADC Resolution
The MCP9800/1/2/3 provides access to select the ADC
resolution from 9-bit to 12-bit using bit 6 and bit 5 of the
CONFIG register. The user can gain better insight into
the
trends
and
characteristics
of
the
ambient
temperature by using a finer resolution. Increasing the
resolution
also
reduces
the
quantization
error.

Summary of Power-up Default
The MCP9800/1/2/3 has an internal Power-on Reset
(POR) circuit. If the power supply voltage VDD glitches
down to the 1.7V (typ.) threshold, the device resets the
registers to the power-up default settings.
Table 4-2 shows the power-up default summary.
