frequency can corrected to 4 MHz. These bits can be considered the fine trimming of the
frequency. Sometimes the device frequency at the uncalibrated point cannot be corrected to 4
MHz by the fine trimming of the CAL3:CAL0 bits value. Therefore two additional bits are available
which give a large frequency offset (positive and negative) to move the frequency within the
range where the fine trimming can work. These bits are the CALSLW and CALFST bits, which
offset the internal RC frequency. The action of these bits are shown in
