Section 10 16-Bit Timer Pulse Unit (TPU)
10.4.4
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 upon overflow/underflow
of TCNT_2 (TCNT_5) as set in the TPSC0 to TPSC2 bits in TCR.
Underflow occurs only when the lower 16-bit TCNT is in phase-counting mode.
Table 10.29 shows the register combinations used in cascaded operation.
Note: When phase counting mode is set for channel 1 or 4, the counter clock setting is invalid
