9.4 Operation of 8-Bit Timer/Event Counters 50, 51
9.4.1 8-bit interval timer operation
of the count value preset to 8-bit timer compare register 5n (CR5n).
the TM5n value cleared to 0 and an interrupt request signal (INTTM5n) is generated.
(TCL5n).
The 8-bit timer/event counters operate as interval timers that generate 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 count clock of TM5n can be selected with bits 0 to 2 (TCL5n0 to TCL5n2) of timer clock select register 5n
[Setting]
<1> Set the registers.
<2> After TCE5n = 1 is set, 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. Clear TCE5n to 0 to stop the count operation.
Remark n = 0, 1
• TCL5n: Select count clock.
• CR5n:
• TMC5n: Count operation stop, clear & start mode on match between TM5n and CR5n.
