MCP9808
5.2.3.2
Interrupt Mode
In Interrupt mode, the Alert output is asserted as active-
high   or   active-low   (depending   on   the   polarity
configuration) when T
A
 drifts above or below T
UPPER
and T
LOWER
 limits. The output is deasserted by setting
bit 5 (Interrupt Clear bit) of CONFIG. Shutting down the
device will not reset or deassert the Alert output. This
mode can not be selected when the Alert output is used
as a critical temperature output only, using bit 2 of
CONFIG.
This    mode    is    designed    for    interrupt    driven
microcontroller-based   systems.   The   microcontroller
receiving the interrupt will have to Acknowledge the
interrupt by setting bit 5 of the CONFIG register from the
MCP9808.
5.2.4
TEMPERATURE RESOLUTION
The MCP9808 is capable of providing temperature
data with +0.5癈 to +0.0625癈 resolution. The resolu-
tion can be selected using the Resolution register
(Register 5-7). It is located at address, 00001000b,
and it provides measurement flexibility. A +0.0625癈
resolution is set as a POR default by the factory.
