Hello,

I have two questions.

No1
There is a Hold Delay in the Table.
Does the combination in Description enable the quarter cycle Delay in DDR mode?

No2
QuadSPIx_FLSHCR on 10.2.14.3 has a TDH setting.
Are this setting and Hold Delay in Table 6-50 the same setting?

best regards
Goto

Hello,

   Yes, recommended QuadSPIx_FLSHCR [TDH] settings [should be set to 01
in DDR mode (DDR_EN=1) and set to 00 in SDR mode (DDR_EN=0)]  corresponds
QuadSPI configuration boot parameter Hold Delay.

 

Regards,
Yuri.
