Example of Cascaded Operation Setting Procedure: Figure 10.17 shows an example of the
setting procedure for cascaded operation.
Examples of Cascaded Operation: Figure 10.18 illustrates the operation when TCNT_2
overflow/underflow counting has been set for TCNT_1, when TGRA_1 and TGRA_2 have been
designated as input capture registers, and when 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 10.19 illustrates the operation when TCNT_2 overflow/underflow counting has been set for
TCNT_1 and phase counting mode has been designated for channel 2.

Set the TPSC2 to TPSC0 bits in the channel 1
(channel 4) TCR to B'1111 to select TCNT_2
(TCNT_5) overflow/underflow counting.
Set the CST bit in TSTR for the upper and lower
channel to 1 to start the count operation.
