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.
Always clear the Status Register prior to resuming erase operations. It avoids Status Register

Clear Status Register
The Clear Status Register command clears the status register. It functions independent
of V
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.
Read Configuration Register
The Read Configuration Register (RCR) is used to select the read mode (synchronous or
asynchronous), and it defines the synchronous burst characteristics of the device. To
modify RCR settings, use the Configure Read Configuration Register command (see
Section 6.0, “Command Set” on page
RCR contents can be examined using the Read Device Identifier command, and then
reading from offset 0x05 (see
