We are using processor P1022 in one of our designs . We have selected 16-bit GPCM / 28-bit Address mode. We have connected LAD[0:15] to NOR flash via latch but LAD[16:27] are connected directly to flash . As per the reference manual it seems that in this mode LAD[0:15] drives address and data signals in address and data phase respectively but LAD[16:27] are shown as don't care in data phase. Kindly elaborate what will the state of LAD[16:27] in data phase in 16-bit GPCM / 28-bit Address mode.

 

Card is in fabrication phase and we have just come to know of this issue.We can not make any further changes now.

Kindly clarify will this setup work??
