12.4.4
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 12.44 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 12.44 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 12.7.22, Simultaneous Capture of TCNT_1 and
TCNT_2 in Cascade Connection.
Table 12.45 show the TICCR setting and input capture input pins.
