8. 16-Bit Timer
Example of Phase Counting Mode: Figure 8.30 shows an example of operations in phase
counting mode. Table 8.5 lists the up-counting and down-counting conditions for 16TCNT2.
In phase counting mode both the rising and falling edges of TCLKA and TCLKB are counted. The
phase difference between TCLKA and TCLKB must be at least 1.5 states, the phase overlap must
also be at least 1.5 states, and the pulse width must be at least 2.5 states.
