The input capture function measures the external signal width and period. The content of the TRDi register
(counter) is transferred to the TRDGRji register as a trigger of the TRDIOji (i = 0 or 1, j = either A, B, C, or D)
pin external signal (input capture). Since this function is enabled with a combination of the TRDIOji pin and
TRDGRji register, the input capture function, or any other mode or function, can be selected for each individual
pin.
The TRDGRA0 register can also select fOCO128 signal as input-capture trigger input.
Figure 14.32 shows a Block Diagram of Input Capture Function, Table 14.23 lists the Input Capture Function
Specifications. Figures 14.33 to 14.43 show the Registers Associated with Input Capture Function, and Figure
14.44 shows an Operating Example of Input Capture Function.
