Timer Interface Module (TIM)
6.9.1 TIM Status and Control Register
The TIM status and control register (TSC):
TOF — TIM Overflow Flag Bit
TOIE — TIM Overflow Interrupt Enable Bit
TSTOP — TIM Stop Bit
TRST — TIM Reset Bit

This read/write flag is set when the TIM counter reaches 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.
This read/write bit stops the TIM counter. Counting resumes when TSTOP is cleared. Reset sets the
TSTOP bit, stopping the TIM counter until software clears the TSTOP bit.
Setting this write-only bit resets the TIM counter and the TIM prescaler. Setting TRST has no effect on
any other registers. Counting resumes from $0000. TRST is cleared automatically after the TIM
counter is reset and always reads as logic 0. Reset clears the TRST bit.
1 = TIM counter has reached modulo value
0 = TIM counter has not reached modulo value
1 = TIM overflow interrupts enabled
0 = TIM overflow interrupts disabled
1 = TIM counter stopped
0 = TIM counter active
1 = Prescaler and TIM counter cleared
0 = No effect
Enables TIM overflow interrupts
Flags TIM overflows
Stops the TIM counter
Resets the TIM counter
Prescales the TIM counter clock
Address: T1SC, $0020 and T2SC, $0030
Do not set the TSTOP bit before entering wait mode if the TIM is required
to exit wait mode.
Setting the TSTOP and TRST bits simultaneously stops the TIM counter at
a value of $0000.
