codes, called Extended Device Codes, will be required. Therefore the system may continue reading out these
Extended Device Codes at the address of (BA)0Eh, as well as at (BA)0Fh.
*2: 2223h for VCCQ: 1.8 V(MBM29BS32LF), 2234h for VCCQ: 3.0 V(MBM29BT32LF).
*3: Outputs 01h at protected sector group addresses and outputs 00h at unprotected sector group addresses.
