SPI DMA Changing MAXCNT

[Lakshmi_K]

Dear Sir,

I am using SPIM ,  EasyDMA array list,with following flags

NRF_DRV_SPI_FLAG_NO_XFER_EVT_HANDLER  , NRF_DRV_SPI_FLAG_RX_POSTINC , NRF_DRV_SPI_FLAG_HOLD_XFER&

My sensor gives data ready indication via GPIO INTR.When data ready INTR occurs I need 2 SPIM transfers with different rx lengths.

1.tx len 1 bytes,rx len 480 bytes (read samples)
2.tx len 1 byte, rx len 2 bytes (clear interrupt)

Can I change the MAXCNT before each   nrf_spim_task_trigger(spi.u.spim.p_reg, NRF_SPIM_TASK_START) without effecting the NRF_DRV_SPI_FLAG_RX_POSTINC ?

Thank you

Hi.

Nordic technical support staff is reduced due to the christmas holiday in Norway.
We will be back to full staffing at 6th of January, and might not be able to provide you with an answer before that.

Best regards,
Nordic technical support
