*Advanced information. Subject to change without notice.
Software Reset does not affect EA mode. Reset commands are ignored once programming or erasure has
begun, until the operation is complete. Software Reset does not affect outputs; it serves primarily to return to
Read Mode from an ASO mode or from a failed program or erase operation.
Software Reset may cause a return to Read Mode from undefined states that might result from invalid command
sequences. However, a Hardware Reset may be required to return to normal operation from some undefined
states. There is no software reset latency requirement.
The reset command is executed during the t_WPH period.

Status Monitoring
There are three methods for monitoring EA status. Previous generations of the MYX29GL01GS11DPIV2 used
the methods called Data Polling and Ready/Busy# (RY/BY#) Signal. These methods are still supported by the
MYX29GL01GS11DPIV2. One additional method is reading the Status Register.
5.4.1
Status Register
The status of program and erase operations is provided by a single 16-bit status register. The status is
receiver by writing the Status Register Read command followed by a read access. When the Status Register
read command is issued, the current status is captured (by the rising edge of WE#) into the register and the
ASO is entered. The contents of the status register is aliased (overlaid) on the full memory address space.
Any valid read (CE# and OE# low) access while in the Status Register ASO will exit the ASO (with the rising
edge of CE# or OE# for t_CEPH/t_OEPH time) and return to the address space map in use when the Status
Register Read command was issued.
The status register contains bits related to the results - success or failure - of the most recently completed
Embedded Algorithms (EA):
• Erase Status (bit 5),
• Program Status (bit 4),
• Write Buffer Abort (bit 3),
• Sector Locked Status (bit 1),
• RFU (bit 0).
and, bits related to the current state of any in process EA:
• Device Busy (bit 7),
• Erase Suspended (bit 6),
• Program Suspended (bit 2),
The current state bits indicate whether an EA is in process, suspended, or completed.
