Reference Manual no TXE in SPIx_CR2 Register?

[PGroe.2]

Hi

In your Reference Manual for the STM32F469 at 31.3.11 it says:

A DMA access is requested when the TXE or RXNE enable bit in the SPIx_CR2 register is
set.

But the SPIx_CR2 Register does not have a TXE/RXNE bit, it has a TXEIE/RXNEIE bit which just en-/disables the Interrupt. Is this a typo or on purpose? The only TXE/RXNE bits I found are in the SPI_SR register...

Hello,

The sentence is wrong, and it should be corrected as follow:

“A DMA access is requested when the TXDMAEN or RXDMAEN enable bit in the SPIx_CR2 register is set�?

On my side, I will raise the typo internally for fix.

Thanks for pointing out this error.

Thanks for the fix... It just confused me as electronics beginner 😉
