24 / 81 page  M58WR064T, M58WR064B 24/81 Once set High, the VPP Status bit can only be reset Low by a Clear Status Register command or a hardware reset. If set High it should be reset be- fore a new Program or Erase command is issued, otherwise the new command will appear to fail. Program Suspend Status Bit (SR2). The Pro- gram Suspend Status bit indicates that a Program operation has been suspended in the addressed block. When the Program Suspend Status bit is High (set to ‘1’), a Program/Erase Suspend com- mand has been issued and the memory is waiting for a Program/Erase Resume command. The Pro- gram Suspend Status should only be considered valid when the Program/Erase Controller Status bit is High (Program/Erase Controller inactive). SR2 is set within 5 µs of the Program/Erase Sus- pend command being issued therefore the memo- ry may still complete the operation rather than entering the Suspend mode. When a Program/Erase Resume command is is- sued the Program Suspend Status bit returns Low. Block Protection Status Bit (SR1). The Block Protection Status bit can be used to identify if a Program or Block Erase operation has tried to modify the contents of a locked block. When the Block Protection Status bit is High (set to ‘1’), a Program or Erase operation has been at- tempted on a locked block. Once set High, the Block Protection Status bit can only be reset Low by a Clear Status Register com- mand or a hardware reset. If set High it should be reset before a new command is issued, otherwise the new command will appear to fail. Bank Write/Multiple Word Program Status Bit (SR0). The Bank Write Status bit indicates wheth- er the addressed bank is programming or erasing. In Enhanced Factory Program mode the Multiple Word Program bit shows if a Word has finished programming or verifying depending on the phase. The Bank Write Status bit should only be consid- ered valid when the Program/Erase Controller Sta- tus SR7 is Low (set to ‘0’). When both the Program/Erase Controller Status bit and the Bank Write Status bit are Low (set to ‘0’), the addressed bank is executing a Program or Erase operation. When the Program/Erase Con- troller Status bit is Low (set to ‘0’) and the Bank Write Status bit is High (set to ‘1’), a Program or Erase operation is being executed in a bank other than the one being addressed. In Enhanced Factory Program mode if Multiple Word Program Status bit is Low (set to ‘0’), the de- vice is ready for the next Word, if the Multiple Word Program Status bit is High (set to ‘1’) the device is not ready for the next Word. Note: Refer to Appendix C, Flowcharts and Pseu- do Codes, for using the Status Register. |
