Notes 1. Value when the external clock is used. When a crystal resonator is used, it is 114
s (MIN.).
2. Selection of fsam = fX, fX/4, fX/64 is possible using bits 0 and 1 (PRM00, PRM01) of prescaler mode register
0 (PRM0). However, if the TI00 valid edge is selected as the count clock, the value becomes fsam = fX/8.
