Extended Configuration Register  
Programming the Extended Configuration Register  
The extended configuration register is programmed by issuing the PROGRAM EXTEN-  
DED CONFIGURATION REGISTER command. The desired ECR[15:0] settings are  
placed on A[15:0], while the PROGRAM EXTENDED CONFIGURATION REGISTER SET-  
UP command is placed on the data bus. Upon issuing the SETUP command, the read  
mode of the addressed partition is automatically changed to read status register mode.  
Next, the CONFIRM command is placed on the data bus while the desired settings for  
ECR[15:0] are again placed on A[15:0]. Upon issuing the CONFIRM command, the read  
mode of the addressed partition is automatically switched to read array mode.  
Because the desired ECR value is placed on the address bus, any hardware-connection  
offsets between the host’s address outputs and the device’s address inputs must be tak-  
en into account.  
For example, if the host’s address outputs are aligned to the device’s address inputs  
such that host address bit A1 is connected to address bit A0, the desired register value  
must be left-shifted by one (for example, 2532h << 4A64h) before programming the  
ECR.  
Programming the ECR functions independently of the voltage on VPP  
.
