Is there the Write Protect Pin about SPI in the dm365?

Why I can't find it in the data sheet about SPI?

SPI doesnt support that. You can get it done using a GPIO pin.

Hi Renjith,

Thanks for your help.If I want to write a data to the select chip.I just need to write the register SPIDAT1.

Am I right?

Yes, you are right. You can do chip select using SPIDAT1 register.

I have met another question.When I change the SPI0 to the SPI1,the result is doesn't right anyway.

Is there any difference between SPI0 and SPI1 except the address of the registers?

Thanks and Regards,

By changing between SPI-0 and SPI-1 what exactly you mean. Is the SPI slave device connected to both SPI-0 and SPI-1 controllers? Please give more details.
