DMA Timers (DTIM0–DTIM3)
24.1.2 Features
Each DMA timer module has the following features:
24.2
The following features are programmable through the timer registers, shown in
24.2.1 Prescaler
The prescaler clock input is selected from system clock (divided by 1 or 16) or from the
corresponding timer input, DTINn. DTINn is synchronized to the system clock. The

• Maximum timeout period of 234,562 seconds at 75 MHz (~65 hours)
• 13-ns resolution at 75 MHz
• Programmable sources for the clock input, including external clock
• Programmable prescaler
• Input-capture capability with programmable trigger edge on input pin
• Programmable mode for the output pin on reference compare
• Free run and restart modes
• Programmable interrupt or DMA request on input capture or reference-compare
