Figure 23.20 shows an example of the cascaded operation setting procedure.
Figure 23.20 Cascaded Operation Setting Procedure
(2) Cascaded Operation Example (a)
Figure 23.21 shows the operation when the MTU1.TCNT counter is set for counting at MTU2.TCNT overflow/
underflow and MTU2 is set for phase counting mode 1 while counters MTU1.TCNT and MTU2.TCNT are cascaded.
The MTU1.TCNT counter is incremented by MTU2.TCNT overflow and decremented by MTU2.TCNT underflow.
