Interrupt source
Select the peripheral interrupt that triggers a DMA burst
for the specified channel.
Selecting SEQ1INT or SEQ2IN T generates a m essage:
“Use A DC block to implement the DMA function.” To do so,
open the C280x/C28x3x ADC block, select the Use DMA
(with C28x3x) parameter, select a DMA channel, and
disable the same DMA channel in the Target Preferences
block. Currently, when you use the ADC block to implement
DMA, the corresponding DMA channel settings are not
configurable in the Target Preferences block.
Select XINT1, XINT 2, or XINT13 to con figure GPIO pin 0 to
31 as an external interrupt source. Select XINT3 to XINT7
to confi gure GPIO pin 32 to 63 as an external interrupt
source. F or more information about configuring XIN T,
consult the following references:

Currently, In terrupt s ource does not support items TINT0
through MREVTB in the drop-down menu.
The Interrupt s ource parameter corresponds to bit 4-0
(PERINTSEL) in the Mode Register (MODE).
