The
Temperature Hysteresis register that contains a 9-bit
data in two’s compliment format. This register is used
to set a hysteresis for the T
represents a minimum temperature limit. If the ambient
temperature drifts below the specified limit, the
MCP9800/1/2/3 asserts an alert output (refer to
Section 5.3.4.3 “ALERT Output
This register uses the nine Most Significant bits (MSbs)
and all other bits are “don’t cares”.
