Suspension during Erasure (Erasure Priority Mode)
Figure 26.23 shows the suspend operation of erasure when the erasure suspend mode is set to the erasure priority mode
(ESUSPMD bit in FCPSR is 1). The control method of erasure pulses in erasure priority mode is the same as that of
programming pulses for the programming suspend processing.
If the FCU receives a P/E suspend command while an erasure pulse is being applied, the FCU definitely continues
applying the pulse. In this mode, required time for the whole erasure processing can be reduced as compared with the
suspension priority mode because the reapplication of erasure pulses does not occur when a P/E resume command issued.
