Hi

FlexBus's FB_AD1~FB_AD18, which should  been connected to SRAM's A0~A17 .

The PCB board has been completed, and then we need to replace the SRAM . The new SRAM's address line is one pin less than the old. It has changed a NC pin in the middle of the address line.

So FB_AD1~FB_AD5 is connected to A0~A4, FB_AD6 is connected to NC useless, FB_AD7~FB_AD18 is connected to A5~A16. I want to ask, can it be used normally?

Thanks
