Part 2: Flash Device Operations
Special Flash Read States
94
Intel PXA27x Processor Family Memory Subsystem
Always clear the Status Register prior to resuming erase operations to avoid Status Register
ambiguity when issuing commands during Erase Suspend. If a command sequence error occurs
during an erase-suspend state, the Status Register contains the command sequence error status
(SR[7,5,4] are set). When the erase operation resumes and finishes, possible errors during the erase
operation cannot be detected by the Status Register because it contains the previous error status.
15.1.1
Flash Clear Status Register
The flash Clear Status Register command clears the status register, leaving all partition read states
unchanged. It functions independent of F-VPP. The Write State Machine (WSM) sets and clears
SR[7,6,2,0], but it sets bits SR[5:3,1] without clearing them. The Status Register should be cleared
before starting a command sequence to avoid any ambiguity. A flash reset also clears the Status
Register.

Flash Write Status (DWS)
0 = Flash is busy; program or erase cycle in progress; SR.0 valid.
1 = Flash is ready; SR[6:1] are valid.
6
Erase Suspend Status
(ESS)
0 = Erase suspend not in effect.
1 = Erase suspend in effect.
5
Erase Status (ES)
0 = Erase successful.
1 = Erase fail or program sequence error when set with SR[4,7].
4
Program Status (PS)
0 = Program successful.
1 = Program fail or program sequence error when set with SR[5,7]
3
F-VPP Status (F-VPPS)
0 = F-VPP within acceptable limits during program or erase operation.
1 = F-VPP ≤ VPPLK during program or erase operation.
2
Program Suspend Status
(PSS)
0 = Program suspend not in effect.
1 = Program suspend in effect.
1
Block Locked Status
(BLS)
0 = Block not locked during program or erase.
1 = Block locked during program or erase; operation aborted.
0
Partition Write Status
(PWS)
DWS PWS
0
= Program or erase operation in addressed partition.
