LS1043A GPCM Porgram 模式

[shawn_tao]

你好，LS1043A的GPCM模式下，non-burst的写时序，可否利用WE的下降沿作为采样数据的标准？

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)

[shawn_tao]

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?

Yes, you can.

Refer to the QorIQ LS1043A Reference Manual, Figure 25-43. Normal GPCM program operation - non-burst mode
