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:

• TMS320x2833x, 2823x External Interface (XINTF) User’s

Guide, Literature Number: SPRU949, available on the

TI Web site.

• TMS320x2833x System Control and Interrupts,Literature

Number: SPRUFB0, available on the TI Web site.

• The C280x/C28x3x GPIO Digital Inputand C280x/C28x3x

GPIO Digital O utput block reference sections in the

Target Support Package TC2 User’s Guide.

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).
