Status Register
sequence error occurs during an ERASE SUSPEND, the status register contains the com-
mand sequence error status (SR[7,5,4] set). When the ERASE operation resumes and fin-
ishes, possible errors during the operation cannot be detected via the status register be-
cause it contains the previous error status.
3. When bits 5:4 indicate a PROGRAM/ERASE operation error, either a CLEAR STATUS REG-
ISTER 50h) or a RESET command must be issued with a 15µs delay.
Clear Status Register
The CLEAR STATUS REGISTER command clears the status register. It functions inde-
pendently of VPP. The device sets and clears SR[7,6,2], but it sets bits SR[5:3,1] without
clearing them. The status register should be cleared before starting a command se-
quence to avoid any ambiguity. A device reset also clears the status register.
