Sector Erase Suspended Operation
This section explains the sector erase suspended operation.
When the sector erase suspended command is sent during sector erase, the flash memory makes a
transition to the sector erase suspended state and temporarily suspends the erase operation.
By sending the erase restart command, the flash memory is returned to the sector erase state and can
restart the suspended erase operation.
Sector Erase Suspended Operation
Sector erase is suspended in the following steps:
1. Write the sector erase suspended command to an address of even number within the address range
of the flash memory during the erasing operation.
2. Confirm Flash Status Register (FSTR).
Issuing the sector erase suspended command, the RDY bit and ESPS bit are set to "0" and "1"
respectively. Under this condition, memory cells of a sector other than a sector to be erased are
could be read and written.
Notes:
−
See Section "3.1 Automatic Algorithm" for details on the sector erase suspended command.
−
When a sector to be erased is read after a sector erase suspend, the value of the sector is
undefined.
