violated, i.e. the suspend requests come repeatedly and too quickly, no forward progress
is made by the Erase Flash Sector algorithm. The resume/suspend sequence runs
indefinitely without completing the erase.
29.4.11.7.3 Aborting a Suspended Erase Flash Sector Operation
The user may choose to abort a suspended Erase Flash Sector operation by clearing the
ERSSUSP bit prior to clearing CCIF for the next command launch. When a suspended
operation is aborted, the flash memory module starts the new command using the new
FCCOB contents.
Note
Aborting the erase leaves the bitcells in an indeterminate,
partially-erased state. Data in this sector is not reliable until a
new erase command fully completes.
The following figure shows how to suspend and resume the Erase Flash Sector operation.
