11.4.4
In cascaded operation*, two 16-bit counters for different channels are used together as a 32-bit
counter.
This function works by counting the channel 1 (channel 4) counter clock at overflow/underflow of
TCNT_2 (TCNT_5) as set in bits TPSC2 to TPSC0 in TCR.
Underflow occurs only when the lower 16-bit TCNT is in phase-counting mode.
Table 11.29 shows the register combinations used in cascaded operation.
Notes: When phase counting mode is set for channel 1 or 4, the counter clock setting is invalid
