7.5.2 External event counter operation
by using 8-bit timer counter 5n (TM5n).
incremented. Either the rising edge or falling edge can be specified as the valid edge.
cleared to 0, and an interrupt request signal (INTTM5n) is generated.

The external event counter counts the number of clock pulses externally input to the TI50/P24 to TI52/P26 pins
Each time the valid edge specified by timer clock select register 5n (TCL5n) is input, the value of TM5n is
When the count value of TM5n matches the values of corresponding 8-bit compare register 5n (CR5n), TM5n is
Whenever the TM5n value matches the value of CR5n, INTTM5n is generated.
