126 / 166 page  Datasheet 126 of 166 002-12337 Rev. *Y 2022-01-18 256Mb/512Mb/1Gb SEMPER™ Flash HYPERBUS™ interface, 1.8V/3.0V Transaction table PPBENT_3_1 ASO Persistent Protection Bits Persistent Protection Bits ASO Entry transaction allows accessing the Persistent Protection bits (PPB) associated with sectors. This entry transaction does not use a sector address from the entry transaction to overlay. The PPB bit for a sector appears in bit 0 of all word locations in the sector. 3 PGNPPB_2_1 Program Nonvolatile Persistent Protection Bits transaction programs the PPB bit corresponding to a sector with data placed on DQ[7:0]. The PPB bit for a sector appears in bit 0 of all word locations in the sector. 2 ERNPPB_2_1 Erase Nonvolatile Persistent Protection Bits transaction erases all the PPB bits. 2 RSWPPB_3_1 Reset Write to Buffer Abort transaction resets the Write Buffer Abort Status Flag (WRBFAB - STRV[3]) in the Status Register caused by a PPB program failure. 3 RDNPPB_1_1 Read Nonvolatile Persistent Protection Bits transaction allows reading the PPB bit corresponding to a sector and places it on DQ[7:0]. The PPB bit for a sector appears in bit 0 of all word locations in the sector. 1 PRTSTS_2_1 Sector Protection Status transaction provides the protection status of the addressed sector. Data out during a SA Protection Status Read indicates whether the indicated sector is protected in bits 0–2: Bit 0 – Indicates whether the indicated sector is protected (0 = protected, 1 = unpro- tected). Bit 1 – Protected using the sector’s DYB bit (0 = protected, 1 = unprotected). Bit 2 – Protected using the sector’s PPB bit (0 = protected, 1 = unprotected). Bits 3 through 15 are all 1s. 2 ASOEXT_1_1 ASO Exit transaction returns the device to reading memory array data mode when device is in an ASO. If any of the ASO Entry commands were issued, an ASO Exit command must be issued to reset the device into Read mode. 1 PPLENT_3_1 ASO PPB Lock Persistent Protection Lock ASO Entry transaction allows accessing the global Persistent Protection Lock bit. This entry transaction does not use a sector address from the entry transaction to overlay. The global Persistent Protection Lock bit appears in bit 0 of all word locations in the device. 3 CLVPPL_2_1 Clear Volatile Persistent Protection Lock transaction clears the global Persistent Protection Lock bit. 2 RDVPPL_1_1 Read Volatile Persistent Protection Lock transaction allows reading the global Persistent Protection Lock bit and places it on DQ[7:0]. The PPL bit appears in bit 0 of all word locations in the sector. 1 ASOEXT_1_1 ASO Exit transaction returns the device to reading memory array data mode when device is in an ASO. If any of the ASO Entry commands were issued, an ASO Exit command must be issued to reset the device into Read mode. 1 DYBENT_3_1 ASO Dynamic Protection Bits Dynamic Protection Bits ASO Entry transaction allows accessing the Dynamic Protection bits (DYB) associated with sectors. This entry transaction does not use a sector address from the entry transaction to overlay. The DYBB bit for a sector appears in bit 0 of all word locations in the sector. 3 STVDYB_2_1 Set Volatile Dynamic Protection Bit transaction sets the DYB bit corresponding to a sector with data placed on DQ[7:0]. The DYB bit for a sector appears in bit 0 of all word locations in the sector. 2 CLVDYB_2_1 Clear Volatile Dynamic Protection Bit transaction clears the DYB bit corre- sponding to a sector with data placed on DQ[7:0]. The DYB bit for a sector appears in bit 0 of all word locations in the sector. 2 RDVDYB_1_1 Read Volatile Dynamic Protection Bit transaction allows reading the DYB bit corresponding to a sector and places it on DQ[7:0]. The DYB bit for a sector appears in bit 0 of all word locations in the sector. 1 PRTSTS_2_1 Sector Protection Status transaction provides the protection status of the addressed sector. Data out during a SA Protection Status Read indicates whether the indicated sector is protected in bits 0–2: Bit 0 – Indicates whether the indicated sector is protected (0 = protected, 1 = unpro- tected). Bit 1 – Protected using the sector’s DYB bit (0 = protected, 1 = unprotected). Bit 2 – Protected using the sector’s PPB bit (0 = protected, 1 = unprotected). Bits 3 through 15 are all 1s. 2 ASOEXT_1_1 ASO Exit transaction returns the device to reading memory array data mode when device is in an ASO. If any of the ASO Entry commands were issued, an ASO Exit command must be issued to reset the device into Read mode. 1 Table 120 HYPERBUS™ transaction description (Continued) Transaction name Description Cycles |
