Freescale Semiconductor
Since the IRC1M frequency is not a linear function of the temperature, but more like a
parabola, the above relative variation is only an indication and should be considered with
care.
Be aware that the output frequency varies with the TC trimming. A frequency trimming
correction is therefore necessary. The values provided in
ambient temperature which can vary from device to device.
