An erase suspend operation is initiated by setting the FLASH_MCR[ESUS] bit. FLASH_MCR[ESUS]
can be set to a 1 at any time when FLASH_MCR[ERS] and FLASH_MCR[EHV] are high and
FLASH_MCR[PGM] is low. A 0 to 1 transition of FLASH_MCR[ESUS] causes the flash module to start
the sequence which places it in erase suspend. The user must wait until FLASH_MCR[DONE] = 1 before
the module is suspended and further actions are attempted. After it is suspended, the array can be read or
a program sequence can be initiated (erase-suspended program). Before initiating a program sequence the
user must first clear FLASH_MCR[EHV]. If a program sequence is initiated the value of the
FLASH_MCR[PEAS] is not reset. These values are fixed at the time of the first interlock of the erase.
Flash core reads while FLASH_MCR[ESUS] = 1 from the blocks being erased return indeterminate data.
The erase operation is resumed by clearing the FLASH_MCR[ESUS] bit. The flash continues the erase
sequence from one of a set of predefined points. This can extend the time required for the erase operation.
WARNING
In an erase-suspended program, programming flash locations in blocks
which were being operated on in the erase can corrupt flash core data.
