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

Figure 7-27. Inﬂuence of TCTRIM[3:0] on the Temperature Coefﬁcient

TCTRIM[3:0]=0x1000 or 0x0000 (nominal TC)
