7.4 Operations of 8-Bit Timer/Event Counters 50 and 51
7.4.1 Operation as interval timer
of the count value preset to 8-bit timer compare register 5n (CR5n).
TM5n value cleared to 0 and an interrupt request signal (INTTM5n) is generated.
(TCL5n).
190
8-bit timer/event counter 5n operates as an interval timer that generates interrupt requests repeatedly at intervals
When the count value of 8-bit timer counter 5n (TM5n) matches the value set to CR5n, counting continues with the
The count clock of TM5n can be selected with bits 0 to 2 (TCL5n0 to TCL5n2) of timer clock selection register 5n
<1> Set the registers.
<2> After TCE5n = 1 is set, the count operation starts.
<3> If the values of TM5n and CR5n match, INTTM5n is generated (TM5n is cleared to 00H).
<4> INTTM5n is generated repeatedly at the same interval.
Caution Do not write other values to CR5n during operation.
Remark Interval time = (N + 1)
