Notes 1. Use this product in a voltage range of 2.2 to 5.5 V because the detection voltage (VPOC) of the power-on

clear (POC) circuit is 2.1 V

±0.1 V.

2. Selection of fsam = fXP, fXP/4, or fXP/256 is possible using bits 0 and 1 (PRM000, PRM001) of prescaler

mode register 00 (PRM00). Note that when selecting the TI000/TI010 valid edge as the count clock, fsam =

fXP.
