HYPERBUS™ interface, 1.8V/3.0V

Features

4.12.1.2

Erase suspend

The Erase Suspend command allows the system to interrupt a sector erase operation and then read data from,

or program data to, the Flash Memory Array. This command is valid only during sector erase operation. The Erase

Suspend command is ignored if written during the chip erase operation.

• Erase Suspend is valid only during a sector erase operation.

• The Erase operation Suspend status flag (SPI - ERASES STR2V[1], HYPERBUS™ ERASES STRV[6]) can be used to

determine if an erase operation has been suspended or was completed at the time RDYBSY changes to 0.

• A Bulk Erase operation cannot be suspended.

• An Erase operation can be suspended to allow a program operation or a read operation. After an

erase-suspended program operation is complete, the device returns to the erase-suspend mode.

• A new erase operation is not allowed with an already suspended erase, program, or data integrity check

operation. An erase command is ignored in this situation.

• If a program failure occurs during erase suspend the Status Register Clear or Software Reset transactions will

return the device to the erase suspended state.

• Reading at any address within an erase-suspended sector produces undetermined data.

4.12.1.3

Data integrity check suspend - Legacy SPI only

• Data Integrity Check Suspend is valid only during a Data Integrity Check Calculation operation.

• The Memory Array Data Integrity Check CRC Suspend Status Flag (SPI - DICRCS STR2V[4], HYPERBUS™ - DICRCS

STRV[8]) can be used to determine if a data integrity check operation has been suspended or was completed at

the time RDYBSY changes to 0.

• A data integrity check operation can be suspended to allow a read operation.

• The time required for the suspend operation to complete is tPEDS.

The system can determine the status of the program operation by reading the RDYBSY bit in the Status Register

1, just as in the standard program operation.

Table 56 lists the transactions allowed during the suspend operation.
