Timer Interface Module (TIM)
15.9 I/O Registers
15.9.1 TIM Status and Control Register
Advance Information

Address:
These I/O registers control and monitor operation of the TIM:
The TIM status and control register (TSC):
TOF — TIM Overflow Flag 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
TIM status and control register, TSC
TIM control registers, TCNTH and TCNTL
TIM counter modulo registers, TMODH and TMODL
TIM channel status and control registers, TSC0 and TSC1
TIM channel registers, TCH0H, TCH0L, TCH1H, and TCH1L
Enables TIM overflow interrupts
Flags TIM overflows
Stops the TIM counter
Resets the TIM counter
Prescales the TIM counter clock
