High-resolution timer (HRTIM) RM0440
946/2126 RM0440 Rev 4
14 interrupts can be generated by each timing unit:
• Delayed protection triggered
• Counter reset or roll-over event
• Output 1 and output 2 reset (transition active to inactive)
• Output 1 and output 2 set (transition inactive to active)
• Capture 1 and 2 events
• Timing unit registers update
• Repetition event
• Compare 1 to 4 event
8 global interrupts are generated for the whole HRTIM:
• System fault and fault 1 to 6 (regardless of the timing unit attribution)
• DLL calibration done
• Burst mode period completed
The interrupt requests are grouped in 8 vectors as follows:
• hrtim_it1: master timer interrupts (master update, sync Input, repetition, MCMP1..4)
and global interrupt except faults (burst mode period and DLL ready interrupts)
• hrtim_it2: TIMA interrupts
• hrtim_it3: TIMB interrupts
• hrtim_it4: TIMC interrupts
• hrtim_it5: TIMD interrupts
• hrtim_it6: TIME interrupts
• hrtim_it7: TIMF interrupts
• hrtim_it8: Dedicated vector all fault interrupts to allow high-priority interrupt handling
Table 239 is a summary of the interrupt requests, their mapping and associated control, and
status bits.
