DMA Timers (DTIM0–DTIM3)
21.1
This chapter describes the configuration and operation of the four direct memory access (DMA) timer
modules (DTIM0, DTIM1, DTIM2, and DTIM3). These 32-bit timers provide input capture and reference
compare capabilities with optional signaling of events using interrupts or DMA triggers. Additionally,
programming examples are included.
21.1.1
Each DMA timer module has a separate register set for configuration and control. The timers can be
configured to operate from the internal bus clock or from an external clocking source using the DTINn
signal. If the internal bus clock is selected, it can be divided by 16 or 1. The selected clock source is routed
to an 8-bit programmable prescaler that clocks the actual DMA timer counter register (DTCNn). Using the
DTMRn, DTXMRn, DTCRn, and DTRRn registers, the DMA timer may be configured to assert an output
signal, generate an interrupt, or request a DMA transfer on a particular event.

Introduction
Overview
The designation n appears throughout this section to refer to registers or
signals associated with one of the four identical timer modules: DTIM0,
DTIM1, DTIM2, or DTIM3.
The GPIO module must be configured to enable the peripheral function of
the appropriate pins (refer to
prior to configuring the DMA Timers.
