Read Status Register
Issuing the Read Status Register command places the device in Read Status Register
mode. Subsequent reads output Status Register information on DQ[7:0], and 00h on
DQ[15:8]. The device remains in Read Status Register mode until a different read-
mode command is issued. Performing a program, erase, or block-lock operation also
changes the device’s read mode to Read Status Register mode.
The Status Register is updated on the falling edge of CE, or OE# when CE is active.
Status Register contents are valid only when SR.7 = 1. When WSM is busy, SR.7
indicates the WSM’s state and SR[6:0] are in high-Z state.
The Read Status Register command functions independent of the voltage level on
VPEN.
Read Device Information
Issuing the Read Device Information command places the device in Read Device
Information mode. Subsequent reads output device information on DQ[15:0].
The device remains in Read Device Information mode until a different read command is
issued. Also, performing a program, erase, or block-lock operation changes the device
to Read Status Register mode.
The Read Device Information command functions independent of the voltage level on
VPEN.
