In cascaded operation, two 16-bit counters for different channels are used together as a 32-bit

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 10.44 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 10.44 Cascaded Combinations

For simultaneous input capture of TCNT_1 and TCNT_2 during cascaded operation, additional

input capture input pins can be specified by the input capture control register (TICCR). For input

capture in cascade connection, refer to section 10.7.22, Simultaneous Capture of TCNT_1 and

TCNT_2 in Cascade Connection.
