The DMA transfer stops. No interrupt, however, is generated.
11.4.2
Isochronous endpoints
A DMA transfer to or from an isochronous endpoint can be terminated by any of the
following conditions (for bit names refer to the DMA Configuration register in
Table 32
):
The DMA transfer completes as programmed in the DMA Counter register
(CNTREN = 1)
DMA operation is disabled by clearing bit DMAEN.
