> Can I use the WE falling edge to sample the programmed data?
Yes, you can.
Refer to the QorIQ LS1043A Reference Manual, Figure 25-43. Normal GPCM program operation - non-burst mode
IFC_CSORn_GPCM[BURST_LEN]=000 Non-burst mode
Refer to the QorIQ LS1043A Reference Manual,25.3.7 Chip-Select Option register - GPCM (IFC_CSORn_GPCM)
in non-burst mode, Can I use the WE falling edge to sample the programmed data?
or must use a high speed clock to sample the WE falling edge as a start and then sample the data during the TWP cycle, any other method if I don't have such a high speed clock in my design?
