Using timer’s event counter mode
In hardware, input interrupt signals to the TAi
In software, set the timer’s operating mode to the event counter mode and a value “0000
into the timer register to the effective edge.
The timer’s interrupt request occurs when an interrupt signal (selected effective edge) is input.

timer’s event counter mode.
Using external interrupt’s level sense
In hardware, input a logical sum of multiple interrupt signals (e.g., ‘a’, ‘b’, and ‘c’) to the INT
pin, and input each signal to each corresponding port.
In software, check the ports’ input levels in the INT
of the signals ‘a’, ‘b’, and ‘c’ is input.
