Important Note

Note that the acquisition chain will not operate if VBAT is below 2.4V. The internal reference voltage for the LCD

will not operate below 1.5V. If the internal reference is not used, the LCD voltage generator and the LCD driver will

operate down to 1.2V. The operation range of the different blocks is summarized in Figure 2-7.
