frequency
The frequency is not necessarily linear with the temperature (in most cases
it will not be). The above diagram is meant only to give the direction
(positive or negative) of the variation of the TC, relative to the nominal TC.
Setting TCTRIM[3:0] to 0x0000 or 0x1000 does not mean that the
temperature coefficient will be zero. These two combinations basically
switch off the TC compensation module, which results in the nominal TC of
the IRC1M.
