(2) Example of Operation with Cascaded Connection
Figure 14.16 shows an example of operation with cascaded connection, where TCNT1 is set to
count TCNT2 overflow, TCRA_1 and TCRA_2 are set to be input capture registers, and the TIOC
pin rising edge is selected.
If rising edges are input simultaneously to the TIOCA1 and TIOCA2 pins, the upper 16 bits of 32-
bit data are transferred to TGRA_1 and the lower 16 bits are transferred to TGRA_2.
