Figure 12.19 illustrates the operation when counting upon TCNT_2 overflow/underflow has been
set for TCNT_1, TGRA_1 and TGRA_2 have been designated as input capture registers, and the
TIOC pin rising edge has been selected.
When a rising edge is input to the TIOCA1 and TIOCA2 pins simultaneously, the upper 16 bits of
the 32-bit data are transferred to TGRA_1, and the lower 16 bits to TGRA_2.
Figure 12.20 illustrates the operation when counting upon TCNT_2 overflow/underflow has been
set for TCNT_1, and phase counting mode has been designated for channel 2.
TCNT_1 is incremented by TCNT_2 overflow and decremented by TCNT_2 underflow.
