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
.
