DMA Timers (DTIM0–DTIM3)
24.1
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 triggers.
Additionally, programming examples are included.
24.1.1 Overview
Each DMA timer module has a separate register set for configuration and control. The timers can
be configured to operate from the system clock or from an external clocking source using the
DTINn signal. If the system 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 initiate a DMA transfer on
a particular event.

Freescale Semiconductor
Introduction
is a block diagram of one of the four identical timer modules.
The designation “n” is used 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
Purpose I/O
Module”) prior to configuring the DMA Timers.
