C5505 EMIF App Note

Are you referring to Figure 1-13 in SPRUGU6–March 2010 document?

Regards.

Steve,

Yes Figure 1-13 and Table 1-24 of SPRUGU6-March 2010 seem to have the discrepancy.

Cheers!

Well, EM_CS# rises (goes high) in the Hold period. What discrepancy are you referring to?

Regards.

Table 1-24 states that the
• EM_CS[n] rises (if no more operations are required to complete the current request)
at the "end of the hold period." While in the picture, EM_CS[n] rises at the end of the "strobe period."

Also, if you look in the read section of the strobe mode, EM_CS[n] and EM_OE rise in the "strobe period" not at the "end of the hold period."  

It seems to be, CS should behave the same in both the read and write states.

Thanks. What I see is Figure 1-12 matches Table 1-23. No problem with the read mode. But in the write mode, both the EM_CS# and EM_DQM# in Figure 1-13 do not match the description in Table 1-24. EM_CS# should goes low at the beginning of Setup and rises at the end of Hold on the rising edge of the clock.EM_DQM# should only be active during Strobe period. I will confirm this.

Regards.
