Unlock Cycle 1
Unlock Cycle 2
Yes
No
Last Sector
Selected?
Done?
DQ5 = 1?
Command Cycle 1
Command Cycle 2
Command Cycle 3
Specify first sector for erasure
Error condition (Exceeded Timing Limits)
Status may be obtained by reading DQ7, DQ6 and/or DQ2.
Poll DQ3.
DQ3 = 1?
Each additional cycle must be written within tSEA timeout
Timeout resets after each additional cycle is written
The host system may monitor DQ3 or wait tSEA to ensure
acceptance of erase commands
No limit on number of sectors
Commands other than Erase Suspend or selecting
additional sectors for erasure during timeout reset device
to reading array data
Notes:
1. See Table 12.1 for erase command sequence.
2. See the section on DQ3 for information on the sector erase timeout.
