I would like to ask about WEIM timing of i.MX257.
As for read accessing;
According to Figure49-7 in i.MX25 reference manual, it is shown that 2 cycles of wait time is inserted by setting WSC=1.
Can I understand that the number of inserted wait cycles is defined as WSC+1?
Can I understand that i.MX25 samples a read data at the point where I wrote ‘(2) End’ in the attached figure?
Can I understand that the time from the point of ‘Start’ till Valid Address equals to '1/2*HCLK + WE31'?
As for write accessing;
Could you show me how to calculate the time of ‘write pulse width’ (the period of WE=L)?
Could you show me how to calculate the ‘Data set-up time’ and ‘Data hold time’ which I wrote in the attached file?
