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 counter clock upon overflow/underflow of
TCNT_2 as set in bits TPSC0 to TPSC2 in TCR.
Underflow occurs only when the lower 16-bit TCNT is in phase-counting mode.
Table 11.30 shows the register combinations used in cascaded operation.
Note: When phase counting mode is set for channel 1, the counter clock setting is invalid and the
Table 11.30 Cascaded Combinations
Combination
Channels 1 and 2
counters operates independently in phase counting mode.
