Pulse width measurement

This mode allows to measure the “H” level width of an

external pulse. While keeping the 16-bit timer/event

counter counting (free-running) with the internal clock

input, the external pulse is input though the TI4. Then

the capture function is used to load the UC16 values

into CAP1 and CAP2 at the rising edge and falling

edge of the external trigger pulse, respectively. The

interrupt INT1 occurs at the falling edge of TI4.

The pulse width is obtained from the difference between

the values of CAP1 and CAP2 and the internal clock cycle.

For example, if the internal clock is 0.8 microseconds

and the difference between CAP1 and CAP2 is 100,

the pulse width will be 100 x 0.8 = 80 microseconds.

Figure 3.7 (7). Pulse Width Measurement

Note:

Only in this pulse width measuring mode (T4MOD <CAPM1, 0> =

10), external interrupt INT1 occurs at the falling edge of TI4 pin input. In

other modes, it occurs at the rising edge.

The width of “L” level can be measured from the differ-

ence between the first C2 and the second C1 at the

second INT1 interrupt.
