REGISTERS The device has various sets of Registers: Status, Function, Read, Extended Read and Autoboot. When the register is read continuously, the same data is output repeatedly until CE# goes HIGH. 6.1 STATUS REGISTER Status Register Format and Status Register Bit Definitions are described in Table 6.1 & Table 6.2. Table 6.1 Status Register Format Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0 SRWD QE BP3 BP2 BP1 BP0 WEL WIP Default 0 0 0 0 0 0 0 0 Table 6.2 Status Register Bit Definition Bit Name Definition Read- /Write Type Bit 0 WIP Write In Progress Bit: "0" indicates the device is ready(default) "1" indicates a write cycle is in progress and the device is busy R Volatile Bit 1 WEL Write Enable Latch: "0" indicates the device is not write enabled (default) "1" indicates the device is write enabled R/W1 Volatile Bit 2 BP0 Block Protection Bit: (See Table 6.4 for details) "0" indicates the specific blocks are not write-protected (default) "1" indicates the specific blocks are write-protected R/W Non-Volatile Bit 3 BP1 Bit 4 BP2 Bit 5 BP3 Bit 6 QE Quad Enable bit: “0” indicates the Quad output function disable (default) “1” indicates the Quad output function enable R/W Non-Volatile Bit 7 SRWD Status Register Write Disable: (See Table 7.1 for details) "0" indicates the Status Register is not write-protected (default) "1" indicates the Status Register is write-protected R/W Non-Volatile Note1: WEL bit can be written by WREN and WRDI commands, but cannot by WRSR command. The BP0, BP1, BP2, BP3, QE, and SRWD are non-volatile memory cells that can be written by a Write Status Register (WRSR) instruction. The default value of the BP0, BP1, BP2, BP3, QE, and SRWD bits were set to “0” at factory. The Status Register can be read by the Read Status Register (RDSR). The function of Status Register bits are described as follows: WIP bit: Write In Progress (WIP) is read-only, and can be used to detect the progress or completion of a Program, Erase, or Write/Set Non-Volatile/OTP Register operation. WIP is set to “1” (busy state) when the device is executing the operation. During this time the device will ignore further instructions except for Read Status/Function/Extended Read Register and Software/Hardware Reset instructions. In addition to the instructions, an Erase/Program Suspend instruction also can be executed during a Program or an Erase operation. When an operation has completed, WIP is cleared to “0” (ready state) whether the operation is successful or not and the device is ready for further instructions. WEL bit: Write Enable Latch (WEL) indicates the status of the internal write enable latch. When WEL is “0”, the internal write enable latch is disabled and the write operations described in Table 6.3 are inhibited. When WEL is “1”, the Write operations are allowed. WEL bit is set by a Write Enable (WREN) instruction. Each Write Non-Volatile Register, Program and Erase instruction must be preceded by a WREN instruction. The volatile register related commands such as the Set Volatile Read Register and the Set Volatile Extended Read Register don’t require to |
