9-15. 4 Byte Address Command Set
The operation of 4-byte address command set was very similar to original 3-byte address command set. The
only different is all the 4-byte command set request 4-byte address (A31-A0) followed by instruction code. The
command set support 4-byte address including: READ4B, Fast_Read4B, QREAD4B, 4READ4B, PP4B, 4PP4B,
SE4B, BE32K4B, BE4B. Please note that it is not necessary to issue EN4B command before issuing any of 4-byte
command set.
