Erase Suspend (Read/Write)
ESUS is used to indicate that the Flash Memory module is in Erase Suspend or in the process
of entering a Suspend state. The Flash Memory module is in Erase Suspend when ESUS=1
and DONE=1.
– ESUS can be set high only when ERS and EHV are high and PGM is low.
– 0–1 transition of ESUS starts the sequence which sets DONE and places the flash in Erase
30 – ESUS can be cleared only when DONE and EHV are high and PGM is low.
ESUS – 1–0 transition of ESUS with EHV=1 starts the sequence which clears DONE and returns the
The Flash Memory module cannot exit Erase Suspend and clear DONE while EHV is low.
In case of Program Suspend while in Erase Suspend (PSUS=1, ESUS=1), ESUS cannot be
cleared first.
ESUS is cleared on reset.
0 Erase sequence is not suspended.
1 Erase sequence is suspended.
