Always clear the Status Register prior to resuming erase operations. Avoid Status
Register ambiguity when issuing commands during Erase Suspend. If a command
sequence error occurs during an erase-suspend state, the Status Register contains the
command sequence error status (SR[7,5,4] set). When the erase operation resumes
and finishes, possible errors during the erase operation cannot be detected via the
Status Register because it contains the previous error status.
15.1.1
Clear Status Register
The Clear Status Register command clears the status register, leaving all partition read
states unchanged. It functions independent of VPP. The Write State Machine (WSM) sets
and clears SR[7,6,2,0], but it sets bits SR[5:3,1] without clearing them. The Status
Register should be cleared before starting a command sequence to avoid any
ambiguity. A device reset also clears the Status Register.
15.2
Read Device Identifier
The Read Device Identifier command instructs the addressed partition to output
manufacturer code, device identifier code, block-lock status, protection register data,
or configuration register data when that partition’s addresses are read (see Section 9.2,
“Device Commands” on page 40 for details on issuing the Read Device Identifier
ID codes” on page 71 show the address offsets and data values for this device.
Issuing a Read Device Identifier command to a partition that is programming or erasing
places that partition in the Read Identifier state while the partition continues to
program or erase in the background.
