Targ et Preferences
Note When you select Use DMA (with C28x3x) the
C280x/C28x3x ADC block:
• If the AD C block Module is
A or A and B, Interrup t
source is
SEQ1INT.
• If the ADC block Module is
B, Interrupt source is
SEQ2INT.
External pin(GPIO)
When Interrupt source is set to an external interface
(XINT[#]), specify the GPIO pin number from which the
interrupt originates.
This param eter corresponds to the GPIO XINTn, XNMI
Interrupt Select (GPIOXINTnSE L, GPIOXNMISEL)
Registers. For more information, consult the TMS320x2833x
System Control and Interrupts Reference Guide,Literature
Number SPRUFB0, available from the TI Web site.
Generate interrup t
Enable this parameter to have the DMA channel send an
interrupt to the CPU via the PIE at the beginning or end of
adatatransfer.
This parameter corresponds to bit 15 (CHINTE) and bit 9
(CHINTMODE) in the Mode Register (MODE).
Note When you select Use DMA (with C28x3x) the
C280x/C28x3x ADC block, the DMA channel generates an
interrupt at the end of the data transfer.
