16.0 Registers
16.1 REGISTER WARNINGS
In most cases, reserved registers and register bits return zero when read. This should not be relied upon, since reserved registers
can be used for future expansion of the LM93 functions.
Some registers have “N/D” for their default value. This means that the power-up default of the register is not defined. In the case
of value registers, care should be taken to ensure that software does not read a value register until the associated measurement
function has acquired a measurement. This applies to temperatures, voltages, fan RPM, and PROCHOT monitoring. In the case
of other registers, such as fan control settings, N/D means that software must initialize these registers to ensure they have a
known value before setting the START bit in the LM93 Configuration register.
