Timer Module Input Characteristics
Four-bit synchronizer circuits determine the shortest input pulses that can be recognized or the fastest
clock that can be used as the optional external source to the timer counter. These synchronizers operate
from the peripheral clock rate. Table 17 shows timer input timing values.
