7.4.2 Operation as external event counter
counter 5n (TM5n).
Either the rising or falling edge can be selected.
and an interrupt request signal (INTTM5n) is generated.
The external event counter counts the number of external clock pulses to be input to the TI5n pin by 8-bit timer
TM5n is incremented each time the valid edge specified by timer clock selection register 5n (TCL5n) is input.
When the TM5n count value matches the value of 8-bit timer compare register 5n (CR5n), TM5n is cleared to 0
Whenever the TM5n value matches the value of CR5n, INTTM5n is generated.
<1> Set each register.
<2> When TCE5n = 1 is set, the number of pulses input from the TI5n pin is counted.
<3> When the values of TM5n and CR5n match, INTTM5n is generated (TM5n is cleared to 00H).
<4> After these settings, INTTM5n is generated each time the values of TM5n and CR5n match.
Note 8-bit timer/event counter 50: PM17
Remark For how to enable the INTTM5n signal interrupt, see CHAPTER 19 INTERRUPT FUNCTIONS.
