9.4 Interrupts
Each timer has its own top-level NVIC interrupt. Writing 1 to the INT_TIMx bit in the INT_CFGSET register
enables the TIMx interrupt, and writing 1 to the INT_TIMx bit in the INT_CFGCLR register disables it. Chapter
11, Interrupt System describes the interrupt system in detail.
Several kinds of timer events can generate a timer interrupt, and each has a status flag in the INT_TIMxFLAG
register to identify the reason(s) for the interrupt:
Clear bits in INT_TIMxFLAG by writing a 1 to their bit position. When a channel is in capture mode, reading the
TIMx_CCRy register will also clear the INT_TIMCCRyIF bit.
The INT_TIMxCFG register controls whether or not the INT_TIMxFLAG bits actually request a top-level NVIC
timer interrupt. Only the events whose bits are set to 1 in INT_TIMxCFG can do so.
If an input capture or output compare event occurs and its INT_TIMMISSCCyIF is already set, the corresponding
capture/compare missed flag is set in the INT_TMRxMISS register. Clear a bit in the INT_TMRxMISS register by
writing a 1 to it.
INT_TIMTIF – set by a rising edge on an external trigger, either edge in gated mode
INT_TIMCCRyIF – set by a channel y input capture or output compare event
INT_TIMUIF – set by a UEV
