Hello,
I have a curious behavior using SPI peripheral in TMS320F28379D.
I am using RX interrupt with 16 FIFO and 16 bytes.
The RX ISR trigger is triggered, in this interrupt, I read the 16 words FIFO, and I send it back,
The first word of the writing back data set to '0', even the first 16 words sent are all 0x00FE
Could you please explain to me why the first word is 0?
I am using SPI A and SPI B with an external connection.
Thank you in advance,
S.Tarik,
