5.1.3
The MCP98242 has a 16-bit read/write Event output
Temperature Upper-Boundary Trip register (T
16-bit Lower-Boundary Trip register (T
16-bit Critical Boundary Trip register (T
contains 11-bit data in two’s complement format
(0.25 °C). This data represents the maximum and
minimum temperature boundary or temperature
window that can be used to monitor ambient
temperature. If this feature is enabled
“Sensor Configuration Register
ambient temperature exceeds the specified boundary
or window, the MCP98242 asserts an Event output.
