9.4.2 External event counter operation
5n (TM5n).
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 TI5n using 8-bit timer counter
TM5n is incremented each time the valid edge specified by timer clock select register 5n (TCL5n) is input. Either
When the TM5n count value matches the value of 8-bit timer compare register 5n (CR5n), TM5n is cleared to 0
Whenever the TM5n count value matches the value of CR5n, INTTM5n is generated.
[Setting]
<1> Set each register
<2> When TCE5n = 1 is set, the number of pulses input from TI5n is counted.
<3> When the values of TM5n and CR5n match, INTTM5n is generated (TM5n is cleared to 00H).
<4> Each time the values of TM5n and CR5n match, INTTM5n is generated.
Remarks 1. N = 00H to FFH

• TCL5n: Edge selection of TI5n input
• CR5n: Compare value
• TMC5n: Count operation stop, clear & start mode on match between TM5n and CR5n, timer F/F inverted
