Section 12 16-Bit Timer Pulse Unit (TPU)
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 (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 12.30 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
Table 12.30 Cascaded Combinations
(1)
Figure 12.17 shows an example of the setting procedure for cascaded operation.

Set bits TPSC2 to TPSC0 in the channel 1
(channel 4) TCR to B'1111 to select TCNT_2
(TCNT_5) overflow/underflow counting.
Set the CST bit in TSTR for the upper and lower
channels to 1 to start the count operation.
