Examples of Cascaded Operation: Figure 10-22 illustrates the operation when counting upon
TCNT2 overflow/underflow has been set for TCNT1, TGR1A, and TGR2A have been designated
as input capture registers, and 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 TGR1A, and the lower 16 bits to TGR2A.
Figure 10-23 illustrates the operation when counting upon TCNT2 overflow/underflow has been
set for TCNT1, and phase counting mode has been designated for channel 2.
TCNT1 is incremented by TCNT2 overflow and decremented by TCNT2 underflow.
