8-bit timer/event counter n operates as an interval timer that repeatedly generates interrupts at the interval of the
If the count value in 8-bit timer counter n (TMn) matches the value set in the CRn register, the value of the TMn
Remark
Setting method
Basic operation
<1> Set each register.
<2> When the TMCEn bit of the TMCn register is set to 1, the count operation starts.
<3> When the values of the TMn register and CRn register match, INTTMn is generated (TMn register is
<4> Then, INTTMn is repeatedly generated at the same interval. To stop counting, set TMCEn = 0.
Operation
Operation as interval timer (8 bits)
Caution During interval timer operation, do not rewrite the value of the CRn register.
• TCLn register: Selects the count clock (t).
• CRn register:
• TMCn register: Stops count operation and selects the mode in which clear & start occurs on a match
cleared to 00H).
