Read Operations  
Read Operations  
The following types of data can be read from the device: array data (read array), device  
information (read ID), CFI data (read CFI), and device status (read status register).  
Upon power-up or return from reset, the device defaults to read array mode. To change  
the read mode, the appropriate command must be issued to the device.  
The table below shows the command codes used to configure the device for the desired  
read mode.

Read Array  
Upon power-up or exit from reset, the device defaults to read array mode. Issuing the  
READ ARRAY command places the addressed partition in read array mode and can only  
be issued to a partition that is not actively programming or erasing. Subsequent reads  
output array data from that partition.  
The addressed partition remains in read array mode until a different READ command is  
issued, a PROGRAM or ERASE operation is performed, or a BLOCK LOCK SETUP com-  
mand is issued in that partition, in which case the read mode automatically changes to  
read status.  
To change a partition that is actively programming or erasing to read array mode, first  
issue the SUSPEND command. After the operation has been suspended, issue the READ  
ARRAY command to the partition. When the PROGRAM or ERASE operation is subse-  
quently resumed, the partition will automatically revert back to read status mode.  
The READ ARRAY command functions independently of the voltage level on VPP  
.
Issuing the READ ARRAY command to a partition that is actively programming or eras-  
ing causes subsequent reads from that partition to output invalid data. Valid array data  
is output only after the PROGRAM or ERASE operation has completed.  
Read ID  
Issuing the READ ID command places the addressed partition in read ID mode. Subse-  
quent reads output device information such as manufacturer code, device identifier  
code, block lock status, OTP data, or read configuration register data.  
The addressed partition remains in read ID mode until a different READ command is  
issued, or a PROGRAM or ERASE operation is performed in that partition, in which case  
the read mode automatically changes to read status.  
The READ ID command functions independently of the voltage level on VPP
