10.4.5 Cascade Connection Mode
Cascade connection mode is a function that connects the 16-bit counters of two channels together
to act as a 32-bit counter.
This function operates by using the TPSC2 to TPSC0 bits of the TCR register to set the channel 1
counter clock to count by TCNT2 counter overflow/underflow.
Note: When channel 1 is set to phase counting mode, the counter clock settings become
ineffective.
Table 10.6 shows the cascade connection combinations.
