Program Suspend Status (PSS)
Always clear the Status Register prior to resuming erase operations. It avoids 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.
Clear Status Register
The Clear Status Register command clears the status register. It functions independent
of V
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 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
Bus Cycles” on page
RCR contents can be examined using the Read Device Identifier command, and then
reading from offset 0x05 (see
