USART Signals
Timer/Counter Signals
The inputs have to meet the minimum pulse width and period constraints shown in
and
Table 20-1.
Table 20-2.
Figure 20-4. USART Signals
Due to internal synchronization of input signals, there is a delay between an input event and a
corresponding output event. This delay is 3(t
in Waveform Total-count Detection mode. The inputs have to meet the minimum pulse width and
minimum input period shown in
Table 20-3.
