How to use DDR transaction with S25HS512T

[lushuizhudan]

Hello!

           Now I want to use DDR transaction protocol (4S-4D-4D) with S25HS512T，and then how I would set the flash, which registers or pameraters should be configurated.

Hi @lushuizhudan ,

You can enable the bit QPI-IT in Configuration Register 2 i.e. CFR1V[1] which changes the mode to QPI mode.

Thanks,

I have enabled bit QIO in Configuration Register 2 : CFR2V[6] which change the mode to QPI mode(4-4-4), but data can not be read normally, Does the flash not support this mode(4-4-4) with DDR read transaction?

Hi @lushuizhudan ,

You can use the command mentioned in Table 77 of the datasheet to read. 

Thanks,
