READ MEMORY OperationsThe device supports default reading and writing to an A[MAX:MIN] of A[23:0] (3-byteaddress).Reading and writing to an A[MAX:MIN] of A[31:0] (4-byte address) is also supported. Se-lection of the 3-byte or 4-byte address range can be enabled in two ways: setting thenonvolatile configuration register or entering the ENABLE 4-BYTE ADDRESS MODE orEXIT 4-BYTE ADDRESS MODE commands. Further details for these settings and com-mands are in the respective register and command sections of the data sheet.Note: When the device is set to the default address range of A[23:0], another method forenabling 4-byte addressing is through the extended address register. Details can befound in Nonvolatile and Volatile Registers.3-Byte AddressTo execute READ MEMORY commands, S# is driven LOW. The command code is inputon DQ n, followed by input on DQ n of three address bytes. Each address bit is latched induring the rising edge of the clock. The addressed byte can be at any location, and theaddress automatically increments to the next address after each byte of data is shiftedout; therefore, the entire memory can be read with a single command. The operation isterminated by driving S# HIGH at any time during data output.Don’t CareDQ[0]C ExtendedDQ1Note: 1.C x = 7 + (A[MAX] + 1).READ MEMORY Operations Timing – Single Transfer RateFigure 32: SUBSECTOR and SECTOR ERASE CommandCDQ0CDQ0[1:0]CDQ0[3:0]Extended Dual QuadNote: 1.For extended SPI protocol, C x = 7 + (A[MAX] + 1).For dual SPI protocol, C x = 3 + (A[MAX] + 1)/2.For quad SPI protocol, C x = 1 + (A[MAX] + 1)/4.BULK ERASE Command质量等级领域:宇航级IC 、特军级IC 、超军级IC 、普军级IC 、禁运IC 、工业级IC ，军级二三极管，功率管等;应用领域:航空航天、船舶、汽车电子、军用计算机、铁路、医疗电子、通信网络、电力工业以及大型工业设备祝您:工作顺利，生活愉快!以深圳市美光存储技术有限公司提供的参数为例，以下为N25Q256A13EF840E的详细参数，仅供参考Figure 33: BULK ERASE CommandC DQ0C DQ[1:0]C DQ[3:0]ExtendedDualQuadPROGRAM/ERASE SUSPEND CommandTo initiate the PROGRAM/ERASE SUSPEND command, S# is driven LOW. The com-mand code is input on DQ0. The operation is terminated by the PROGRAM/ERASE RE-SUME command.PROGRAM/ERASE SUSPEND command enables the memory controller to interrupt and suspend an array PROGRAM or ERASE operation within the program/erase latency.If a SUSPEND command is issued during a PROGRAM operation, then the flag status register bit 2 is set to 1. After erase/program latency time, the flag status register bit 7 is also set to 1, showing the device to be in a suspended state, waiting for any operation (see the Operations Allowed/Disallowed During Device States table).If a SUSPEND command is issued during an ERASE operation, then the flag status regis-ter bit 6 is set to 1. After erase/program latency time, the flag status register bit 7 is also set to 1, showing that device to be in a suspended state, waiting for any operation (see the Operations Allowed/Disallowed During Device States table).If the time remaining to complete the operation is less than the suspend latency, the de-vice completes the operation and clears the flag status register bits 2 or 6, as applicable.Because the suspend state is volatile, if there is a power cycle, the suspend state infor-mation is lost and the flag status register powers up as 80h.During an ERASE SUSPEND operation, a PROGRAM or READ operation is possible in any sector except the one in a suspended state. Reading from a sector that is in a sus-pended state will output indeterminate data. The device ignores a PROGRAM com-mand to a sector that is in an ERASE SUSPEND state; it also sets to 1 the flag status reg-ister bit 4: program failure/protection error, and leaves the write enable latch bit un-changed. The WRITE LOCK REGISTER, WRITE VOLATILE CONFIGURATION REGIS-TER, and WRITE ENHANCED VOLATILE CONFIGURATION REGISTER commands are。
