14.2.12 DMA Timer Signals

This section describes the signals of the four DMA timer modules.
14.2.12.1 DMA Timer 0 Input (DTIN0)
The DMA timer 0 input (DTIN0) can be programmed to cause events to occur in DMA
timer 0. It can either clock the event counter or provide a trigger to the timer value capture
logic.
This pin can also be configured as GPIO PTD1, secondary function UCTS1, or secondary
function UCTS0.
14.2.12.2 DMA Timer 0 Output (DTOUT0)
The programmable DMA timer output (DTOUT0) pulse or toggle on various timer events.
This pin can also be configured as GPIO PTD0, secondary function UCTS1, or secondary
function UCTS0.
14.2.12.3 DMA Timer 1 Input (DTIN1)
The DMA timer 1 input (DTIN1) can be programmed to cause events to occur in DMA
timer 1. This can either clock the event counter or provide a trigger to the timer value
capture logic.
This pin can also be configured as GPIO PTD3, secondary function URTS1, or secondary
function URTS0.
14.2.12.4 DMA Timer 1 Output (DTOUT1)
The programmable DMA timer output (DTOUT1) pulse or toggle on various timer events.
This pin can also be configured as GPIO PTD2, secondary function URTS1, or secondary
function URTS0.
14.2.12.5 DMA Timer 2 Input (DTIN2)
The DMA timer 2 input (DTIN2) can be programmed to cause events to occur in DMA
timer 2. It can either clock the event counter or provide a trigger to the timer value capture
logic.
This pin can also be configured as GPIO PTC1, secondary function UCTS1, or secondary
function UCTS0.
14.2.12.6 DMA Timer 2 Output (DTOUT2)
The programmable DMA timer output (DTOUT2) pulse or toggle on various timer events.
This pin can also be configured as GPIO PTC0, secondary function UCTS1, or secondary
function UCTS0.
