Modulo Timer (TIM)
19.8.1 TIM Status and Control Register
Technical Data
Address:
The TIM status and control register:
TOF — TIM Overflow Flag Bit
TOIE — TIM Overflow Interrupt Enable Bit
Reset:
Read:
Write:
•
•
•
•
•
This read/write flag is set when the TIM counter resets to $0000 after
reaching the modulo value programmed in the TIM counter modulo
registers. Clear TOF by reading the TIM status and control register
when TOF is set and then writing a logic 0 to TOF. If another TIM
overflow occurs before the clearing sequence is complete, then
writing logic 0 to TOF has no effect. Therefore, a TOF interrupt
request cannot be lost due to inadvertent clearing of TOF. Reset
clears the TOF bit. Writing a logic 1 to TOF has no effect.
This read/write bit enables TIM overflow interrupts when the TOF bit
becomes set. Reset clears the TOIE bit.
