Hi community.

Our customer has below question.

About DMA of ECSPI,
ECSPI by Configu to SPI of the Master, so it is to transmit only.
( Receive is not performed).

TXFIFO side, as to send data using DMA,
RXFIFO side, ignoring overflow, sending doesn't matter?

(For example, Disable to RXFIFO Overflow Interrupt , do not affect the TX processing?)

Hi Takashi

you are right, RX side can be ignored, possibly disabling

RXFIFO Overflow Interrupt. This should not affect TX processing.

Best regards
