Since the IRC1M frequency is not a linear function of the temperature, but
more like a parabola, the above relative TC variation is only an indication
and should be considered with care.
Be aware that the output frequency vary with TC trimming, A frequency
trimming correction is therefore necessary. The values provided in
Table 7-21
device to device.
Table 7-21. TC trimming of the IRC1M frequency at ambient temperature
are typical values at ambient temperature which can vary from
0 (nominal TC of the IRC1M)
0 (nominal TC of the IRC1M)
