MCP98242
5.1.1
This is a read-only register used to identify the
temperature sensor capability. In this case, the
MCP98242 is capable of providing temperature at
0.25°C resolution, measuring temperature below and
above 0°C, providing ±1°C and ±2°C accuracy over the
active and monitor temperature ranges (respectively)
and providing user-programmable temperature event
boundary trip limits. Register 5-2 describes the
Capability register. These functions are described in
further detail in the following sections.
