NRFX_USBD_CONFIG_DMASCHEDULER_ISO_BOOST

#define NRFX_USBD_CONFIG_DMASCHEDULER_ISO_BOOST

Give priority to isochronous transfers.

This option gives priority to isochronous transfers. Enabling it assures that isochronous transfers are always processed, even if multiple other transfers are pending. Isochronous endpoints are prioritized before the usbd_dma_scheduler_algorithm function is called, so the option is independent of the algorithm chosen.

Set to 1 to activate.

Note

This is an NRF_CONFIG macro.

NRFX_USBD_CONFIG_IRQ_PRIORITY
